Thorlabs offers four Olympus visible imaging objectives with magnifications of 4X, 10X, 20X, and 40X. The achromatic objectives are corrected for red and blue wavelengths and the elements in each objective have an ultra wide broadband AR coating. In addition, they have standard RMS threading, which makes them compatible with many of the microscopy and fiber coupling accessories offered by Thorlabs.
The RMS series of microscope objectives should be used in applications like traditional microscopy, confocal imaging, and fiber coupling. When choosing an infinity-corrected microscope objective, it is important to keep in mind that objectives are often designed to integrate with a particular manufacturer's microscopes and are not necessarily interchangeable due to tube length differences and variations in thread pitch or diameter.

Description
Visible Imaging Objectives
Visible light achromatic objectives designed for imaging applications.
OCT Objective lenses with a telecentric design for supurb off-axis imaging. (1315 ± 65 nm)
Our microscope objectives can be mounted directly to our fiber launch systems, or they can be mounted to any of our flexure or translation stages using a HCS013 RMS mount. Alternatively, these microscope objectives can be easily mounted to our cage systems (using an SM1A3 adapter) or to our lens tubes, thus facilitating the setup of optical systems.

Response from Javier at Thorlabs to kearly500: Thank you for your feedback. We do not have concise values for the damage threshold of these lenses. However, as a guideline, Olympus recommends limiting the power input to <20mW for focused light and <100mW for collimated light.

Hi, Im wondering what the damage threshold is for the RMS40X. Were using it to fiber couple a 2W solid state laser at 532 nm, and I wanted to know if we need to attenuate beforehand.

A response from Adam at Thorlabs to Albert: While it is possible to use the RMS threaded objectives with the DCC1645C, I think we need more information about your application before we confirm. We would need to know information about your object size and distance. I will email you directly to get this information. On a side note, to connect the RMS threaded objective to the DCC1645C, one would need to use a SM1A3(SM1 to RMS threaded adapater), and a SM1A9(SM1 to C-mount threaded adapter).

Dear Sirs,
We are going to develop a digital microscopic imaging system by using your DCC1645C, MAX203, BSC102 and objective lens(RMS Series). I would like to know if it is possible to install RMS lens to DCC1645C and get the microscopic image.
If the answer is not, how we can integrate such kind of imaging systm by using your existing products.
Look forward to getting your advice ASAP.

A response from Adam at Thorlabs: At this time, Olympus does not provide us with information on the focal shift of these lenses. Since we cannot get this information from Olympus, we cannot provide concrete numbers. The RMS40X is designed more for red and blue wavelengths, so the shift from 650-750nm will be slightly larger than that of a typical objective, 3-4um. The focal shift of the C340TME-B lens is 20um over the range of 650-750nm. I noticed that an email address was not provided. If you have further questions, please feel free to respond to the feedback or send an email to techsupport@thorlabs.com.

I am interested in the typical focal shift around 650-750nm. In addition I would like to know the maximum diffraction limited range around 700nm.
I am thinking about this objective or the C340TME-B lens, to collect light from a point like ligth source in the above mentionned wavelength regime.
Thanks

A response from Ken at Thorlabs to plouis: These objectives are primarily designed for blue and red region. However, they still have about 83% transmittance at 800nm so they should work.

I would like to know if it possible to use these lenses for coupling 830 nm light (photons from SPDC) into SM (and MM) fibers using your fiber launch system.

do you have tube lens for these objectives?

In response to dutertes inquiry, we have contacted our optics department. Unfortunately, Olympus does not provide us with transmission curves for their objectives. I apologize that we cannot be of more help to you. Perhaps Olympus would be willing to provide that information if you contacted then directly.

Could you please tell me what are the transmissions for the infinity-corrected microscope objectives UIS2 :
- 4X Microscope Objective, 18.5 mm WD
- 10X Microscope Objective, 10.6 mm WD
- 20X Microscope Objective, 0.4 NA, 1.2 mm WD
- 40X Microscope Objective, 0.65 NA, 0.6 mm WD
At 1064 nm and if it’s possible at 1550 nm.
With best regards,
Charles DUTERTE

Objectives for the Visible Portion of the Spectrum
Allows for Conversion of Instrument to Microscope
Ideal for Imaging or Focusing Laser Light
Lenses are Infinity Corrected
Plan Achromat Design
These infinity-corrected, imaging, visible microscope objectives provide 4X, 10X, 20X, or 40X magnification. With their high numerical apertures (NA) and large magnifications, they are suitable for focusing or collimating laser light. These Olympus objectives are ideal for imaging applications due to their diffraction-limited performance across the entire visible spectrum. Alternatively, they can be used to focus light to a diffraction-limited spot, thus enabling efficient coupling of monochromatic or broadband light into a waveguide or fiber.
Their designation as Plan Achromats indicates that they are flat field and aberration corrected at two different wavelengths in the visible spectrum, leading to better spherical and chromatic corrections and superb field flatness. These achromatic objectives have an ultra wide antireflection coating and standard RMS threading.
The OT1 is a compact objective lens turret with four RMS threaded ports. The housing is primarily constructed of aluminum but has steel inserts at critical points to ensure the durability and precision of the detent mechanism that reproducibly positions the objective lenses with a high degree of accuracy. The mounting interface for the OT1 objective lens turret has SM1 threading so that it can be easily integrated into custom imaging systems built using Thorlabs' Lens Tube and Cage Systems. To mount the OT1 in a cage system use a CP02 or CP02T for a 30 mm cage system and an LCP02 for a 60 mm cage system.
