Features

Trinocular Port Adapters
These adapters integrate the Cerna platform with Thorlabs' 30 mm and 60 mm cage construction systems, making them ideal for creating custom widefield viewing and epi-illumination apparatuses.

Camera Port Adapter
The SM1A58 adapter is designed to allow components with SM1 threading, SM2 threading, or 30 mm cage system compatibility to be mounted to the camera port. This adapter is ideal for inserting custom optics, as well as our scientific cameras, into brightfield and fluorescence microscope systems. 

Condenser Port Adapters
These condenser adapters connect to the condenser holder, allowing DIY light conditioning setups to be integrated into a Cerna microscope.

Epi-Illumination Module Adapter
The SM2A56 adapter allows a collimated illumination source to attach to the epi-illumination module of a Cerna microscope.

Eyepiece Adapter
The SM2N2 adapter replaces the lens element on an eyepiece of the Cerna microscope's trinoculars, allowing custom-built optical detection systems to attach to either eyepiece on the trinoculars.

Note: Thorlabs does not guarantee compatibility with other industry-standard microscopes not mentioned on this wepage.

  • These dovetail designations are specific to Thorlabs products and are not used by other microscope manufacturers.
  • D2N and D2NB dovetails have the same outer diameter and angle, as defined by the drawings below. The D2N designation does not specify a height. The D2NB designation specifies a dovetail height of 0.40" (10.2 mm).

Introduction to Microscope Dovetails

Dovetails are used for mechanical mating and optical port alignment of microscope components. Components are connected by inserting one dovetail into another, then tightening one or more locking setscrews on the female dovetail. Dovetails come in two shapes: linear and circular. Linear dovetails allow the mating components to slide before being locked down, providing flexible positioning options while limiting unneeded degrees of freedom. Circular dovetails align optical ports on different components, maintaining a single optical axis with minimal user intervention.

Thorlabs manufactures many components which use dovetails to mate with our own components or those of other manufacturers. To make it easier to identify dovetail compatibility, we have developed a set of dovetail designations. The naming convention of these designations is used only by Thorlabs and not other microscope manufacturers. The table to the right lists all the dovetails Thorlabs makes, along with their key dimensions.

In the case of Thorlabs’ Cerna® microscopes, different dovetail types are used on different sections of the microscope to ensure that only compatible components can be mated. For example, our WFA2002 Epi-Illuminator Module has a male D1N dovetail that mates with the female D1N dovetail on the microscope body's epi-illumination arm, while the CSS2001 XY Microscopy Stage has a female D1Y dovetail that mates with the male D1Y dovetail on the CSA1051 Mounting Arm.

To learn which dovetail type(s) are on a particular component, consult its mechanical drawing, available by clicking on the red Docs icon (Docs Icon) below. For adapters with a female dovetail, the drawing also indicates the size of the hex key needed for the locking setscrew(s). It is important to note that mechanical compatibility does not ensure optical compatibility. Information on optical compatibility is available from Thorlabs' web presentations.

For customers interested in machining their own dovetails, the table to the right gives the outer diameter and angle (as defined by the drawings below) of each Thorlabs dovetail designation. However, the dovetail's height must be determined by the user, and for circular dovetails, the user must also determine the inner diameter and bore diameter. These quantities can vary for dovetails of the same type. One can use the intended mating part to verify compatibility.

In order to reduce wear and simplify connections, dovetails are often machined with chamfers, recesses, and other mechanical features. Some examples of these variations are shown by the drawings below.

Standard Mechanical Interfaces on DIY Cerna® Components

The table below gives the dovetail, optical component threads, and cage system interfaces that are present on each DIY Cerna component. If a DIY Cerna component does not have one of the standard interfaces in the table, it is not listed here. Please note that mechanical compatibility does not ensure optical compatibility. Information on optical compatibility is available from Thorlabs' web presentations.

  • Additional information on dovetails is available in the Microscope Dovetails tab.
  • This internal SM1 threading is not deep enough for mounting optics.
  • Attach Custom-Built Optical Systems or Detectors to the Camera Port of Thorlabs' Cerna Microscopes
  • Compatible with SM1, SM2, and 30 mm Cage Construction Systems

The SM1A58 is designed so that custom-built optical systems or detectors based on Thorlabs' components may be attached to the camera port of Thorlabs' Cerna Microscopes or Upright Nikon Eclipse Microscopes. This adapter utilizes a male D2N dovetail to secure the adapter to the port. It also features internal SM1 (1.035"-40) threading for Ø1" Lens Tubes, external SM2 (2.035"-40) threading for Ø2" Lens Tubes, and 4-40 tapped holes on 30 mm centers for attaching cage system rods.

Industry-standard C-mount cameras, like Thorlabs' Scientific CCD Cameras, can be attached directly to the internal SM1 threads of the SM1A58 using the SM1A39 external C-Mount to external SM1 adapter, available separately. Internally threaded SM1 Cameras, like Thorlabs' Quantalux®, Kiralux®, and Zelux® cameras, can be easily integrated into microscope systems using the internal SM1 threads or external SM2 threads on the SM1A58 adapter. The internal SM1 threads can be mounted with an SM1 lens tube spacer or an SM1 lens tube coupler with external threads. The external SM2 threads on the SM1A58 are commonly connected with an SM1A2 adapter, which has internal SM2 to external SM1 threads.

Our SM1 or SM2 lens tubes can be used to place the camera at the correct parfocal distance; the exact distance will depend upon the specific trinoculars or other camera ports present on your Cerna microscope.

In addition, an SM1-threaded dust cover (Item # SM1CP2) is included to keep the port closed when not in use.

Two SM2N2 adapters attached to the trinocular eyepieces.
  • Replace Trinocular Eyepiece for DIY Construction
  • Compatible with SM1, SM2, and 30 mm Cage Construction Systems

The SM2N2 Eyepiece Adapter allows custom-built optical detection systems to attach to either eyepiece on the trinoculars of a Cerna Microscope. This adapter replaces the lens element on the eyepiece that sets the image plane at the back of the eyes (see image to the right). Five built-in alignment slots ensure the adapter fits snugly inside the eyepiece without rotation; because of the drop-in nature of this adapter, take care the attached system does not overbalance the 40 g eyepiece adapter when it is inside the trinoculars.

This adapter features internal SM1 (1.035"-40) threading for Ø1" lens tubes; two SM1RR retaining rings are included to secure an optic inside the adapter. The adapter also has external SM2 (2.035"-40) threading for Ø2" lens tubes. The face with the item # engraving has 4-40 tapped holes for 30 mm cage systems.
