Bergamo® II Modules

Thorlabs Bergamo® II microscopes are modular systems that can be customized in the design process to meet the exact needs of the experiment. The modules listed below are displayed in a variety of pre-built examples found on our Configurations tab to help provide a starting point for your design. 

BergamoII Rotating Body

Galvo-Resonant Scanners, Galvo-Galvo Scanners, and Spatial Light Modulators

Bergamo® II microscopes can be configured with one or two co-registered scan paths to propagate, condition, and direct an input laser beam. Each path can utilize a resonant-galvo-galvo scanner, galvo-resonant scanner, galvo-galvo scanner, and/or a spatial light modulator (SLM). These choices allow the user to optimize each experiment as needed for high frame rates, high sensitivity, and/or targeted exposure of the regions of interest.

Resonant-Galvo-Galvo Scanners for Random Access Scanning
Thorlabs offers 8 kHz and 12 kHz resonant-galvo-galvo (RGG) scanners. These scanners enable multiple areas within a single FOV to be imaged at high speed in quick succession. Our 8 kHz scanners utilize the entire field of view and offer a maximum frame rate of 400 fps, while our 12 kHz scanners provide an increased frame rate of 600 fps.

Galvo-Resonant Scanners for High-Speed Imaging
Thorlabs offers 8 kHz and 12 kHz galvo-resonant scanners. Our 8 kHz scanners utilize the entire field of view and offer a maximum frame rate of 400 fps, while our 12 kHz scanners provide an increased frame rate of 600 fps.

Galvo-Galvo Scanners for User-Defined ROI Shapes
Galvo-galvo scanners support user-drawn scan geometries (lines, polylines, squares, and rectangles) and also support custom photoactivation patterns (circles, ellipses, polygons, and points). They offer consistent pixel dwell times for better signal integration and image uniformity.

Spatial Light Modulator for Simultaneous Targeting
Unlike scanners, which physically move from point to point, spatial light modulators (SLMs) use holography to diffract the beam and shape it in a user-defined pattern. This includes general beam shaping as well as the creation of multiple focal points at the FOV; the latter allows multiple sites in a sample to be photoexcited simultaneously.

Figure 1.  The above image was acquired using single-wavelength excitation at 788 nm, while the optimum excitation wavelengths for the two tags are 750 nm and 850 nm.

Fast Switching Using a
Tunable Femtosecond Laser

With an industry-leading tuning speed of up to 4000 nm/s and a wide 720 to 1060 nm tuning range, the Tiberius® Ti:Sapphire Femtosecond Laser is ideal for fast sequential imaging in multiphoton microscopy applications. 

A 25 µm thick sagittal section of an adult rat brain is shown in the images and video to the right. The red channel corresponds to fluorescence from chick anti-neurofilament that is optimally excited at 835 nm, while the green channel corresponds to fluorescence from mouse anti-GFAP that is optimally excited at 750 nm.

Figure 1 shows fluorescence from single-wavelength excitation at 788 nm, which sub-optimally excites the two tags simultaneously. Figure 2 is a composite image of the fluorescence produced by a two-color excitation image sequence acquired at 7 fps where the excitation wavelength was rapidly tuned between 750 and 835 nm. The video in Figure 3 shows the fast-switching used to create the composite image in Figure 2 at 1/16th of the actual speed. When compared to single-wavelength excitation at 788 nm with the same intensity, fast switching offers much higher image contrast as it provides optimal excitation of both fluorophores.

This immunofluorescence sample was prepared by Lynne Holtzclaw of the NICHD Microscopy and Imaging Core Facility, a part of the National Institutes of Health (NIH) in Bethesda, MD.

 

BergamoII Rotating Body
Click to Enlarge

Rotating Bergamo II systems are outfitted with multi-joint articulating periscopes. This periscope's design offers the enhanced flexibility needed to allow the entire scanning system to be tilted with respect to the sample.
BergamoII Non-Rotating Body
Click to Enlarge

Upright Bergamo II systems are equipped with periscopes that permit the microscope's full travel range in X, Y, and Z to be used without compromising the optical performance.

Periscopes

Most lasers used in multiphoton microscopy are delivered by a free-space beam. The Bergamo II's ability to translate the objective around the focal plane in up to four axes (X, Y, Z, and θ) also requires the beam path to translate along the same axes while maintaining alignment. Bergamo II systems overcome this engineering challenge using multi-jointed periscopes.

Super Broadband Scan Optics

Bergamo II microscopes feature proprietary scan optics that are optimized and corrected for excitation wavelengths within the 450 - 1100 nm, 680 - 1600 nm, or 900 - 1900 nm wavelength range, ideal for photostimulation, two-photon imaging, and three-photon imaging, respectively. These broad ranges, extending from the visible well into the near infrared, were chosen to support the latest widely tunable Ti:Sapphire lasers and OPO systems, as well as dual-output lasers such as the Chameleon Discovery.

Our optics take full advantage of the optical designs used in the low-magnification, high-numerical-aperture objectives by filling the back aperture of the objective up to Ø20 mm. This creates an exceptional scan area that lets you find a region of interest more quickly or simply image more cells at once.

Large-Angle Signal Collection Optics

Deriving the most signal from limited photons is the fundamental goal of any detection system. By positioning the PMTs immediately after the objective (a "non-descanned" geometry), light that is scattered by the sample, which therefore appears to originate outside the objective's field of view, still strikes the PMTs and adds to the collected signal. This is a benefit unique to multiphoton microscopy. Collecting beyond the objective's design field of view greatly enhances overall detection efficiency when imaging deep in tissue.

In the epi direction, we offer signal collection anglesa of 8°, 10°, or 14°, while in the transmitted direction, we offer a signal collection anglea of 13°. Our collection modules can optionally be outfitted with mechanical shutters for photoactivation experiments.

Easy-to-Reach Emission Filters and Dichroic Holders

Bergamo II systems are fully compatible with industry-standard fluorescence filter sets that include Ø25 mm fluorescence filters and 25 mm x 36 mm dichroic mirrors. Unlike competing designs, Thorlabs' detector modules have magnetic holders that make it simple and quick to exchange filters for different measurements.

We also offer detection modules for large-area Ø32 mm fluorescence filters and 32 mm x 42 mm dichroics, which support greater collection angles for increased signal.

Detectors in Epi and Transmitted Directions

We employ high-sensitivity GaAsP PMTs in our multiphoton systems, which can offer high quantum efficiency, aiding in imaging weakly fluorescent or highly photosensitive samples. Our PMTs can either be thermoelectrically cooled for improved sensitivity toward weak signals or non-cooled for a smaller package size and greater numerical aperture. Multialkali PMTs are also available.

All Bergamo® II microscopes can be equipped with either two or four detection channels in the epi direction, and/or two detection channels in the forward direction. The user can configure the forward-direction channels to detect the same fluorescent tags as the epi-direction PMTs, raising the microscope's sensitivity toward thin, weakly fluorescent specimens.

A maximum of four channels can be controlled by the software at a given time.

Multi-Axis Controller with Touchscreen

This controller is specifically designed for rotating Bergamo II microscope bodies. It uses knobs to control up to five motorized axes. On rotating systems, a rocker switch changes between fine objective focusing and translation of the elevator base. Each axis can be disabled on an individual basis in order to maintain a location along the desired direction.

The integrated touchscreen lets two spatial locations be saved and retrieved locally. Up to eight spatial locations can be saved on the computer running ThorImage®LS. The touchscreen also reads out the position of every motor.

 

Objectives

Bergamo II microscopes accept infinity-corrected objectives with M34 x 1.0, M32 x 0.75, M25 x 0.75, or RMS threads. Together, these options encompass the majority of low-magnification, high-NA objectives used in multiphoton microscopy. With a large field number of 20, our scan optics completely utilize the optical designs of these specialized objectives, offering enhanced light-gathering ability compared to competing microscopes using the same objectives.

 

Rigid Stand Sample Holders

Thorlabs' Rigid Stands are rotatable, lockable, low-profile platforms for mounting slides, recording chambers, our Z-axis piezo stages, and custom experimental apparatuses. Each fixture is supported by a solid Ø1.5" stainless steel post for passive vibrational damping, which is in turn held to the workstation by the red post holder.

A locking collar maintains the height of the platform, allowing it to easily rotate into and out of the optical path, and a quick-release mechanism holds the post in place once the desired position is achieved.

 

Quantulux and 1.4 Megapixel Scientific Cameras
Click to Enlarge

A Quantulux sCMOS Camera and 1.4 Megapixel Scientific Camera

Scientific Cameras

Our low-noise, scientific-grade CCD, sCMOS, and CMOS cameras were designed for full compatibility with Thorlabs’ multiphoton microscopy systems. Useful for widefield and fluorescence microscopy, they are capable of visualizing in vitro and in vivo samples using reflected light and fluorescence emission. They work in conjunction with the epi-fluorescence module to help locate fiducial markers, and they also enable imaging modalities that do not require laser exposure.

Thorlabs' cameras are driven by our internally developed ThorCam software package. CCD cameras are available in 1.4 MP, 4 MP, 8 MP, and fast-frame-rate versions, the sCMOS camera is available with a 2.1 MP sensor, and our CMOS cameras are available with a 5 MP sensor. Generally speaking, cameras with lower resolution offer higher maximum frame rates. These cameras also feature a separate auxiliary port that permits the image acquisition to be driven by an external electrical trigger signal.

Bergamo® II microscopes are also directly compatible with any camera using industry-standard C-mount or CS-mount threads.

 

Bergamo II with Dodt Contrast

User-Installable Dodt Contrast and DIC Imaging Modules

The modular construction of the Bergamo® II makes it exceptionally easy for the user to convert the microscope between in vitro and in vivo applications. Our user-installable trans-illumination modules for Dodt contrast, laser-scanned Dodt contrast, and differential interference contrast (DIC) take less than 5 minutes to attach or remove from the microscope body. These modules are available for both rotating and upright bodies.

Each option is paired with our basic 3-axis controller, which optimizes the illumination conditions by translating our motorized condenser stage over a 1" range. This versatile design is compatible with air and high-NA oil immersion condensers designed by Nikon.

To complement these modules, we manufacture slim-profile rigid stand sample holders that are ideal for positioning slides between the transmitted light module and the objective.
