High-quality photographic and HD video documentation with the Zeiss slit lamp and Zeiss Surgical microscopes (OPMI) 

The LM digital adapter for Zeiss slit lamps and surgical microscopes (SL120, SL130) makes it possible to produce high-level photographic and video material of up to 36 megapixels using DSLR cameras and system cameras without any difficulty. It is also very easy to transmit live feeds to an HD monitor.

Compared to C-mount cameras with small sensors (1/2”, 1 1/8”, 1 2/5”), digital SLR and system cameras offer great advantages. The most obvious difference is the sensor size. C-mount cameras with small sensors (left-hand image) cannot utilise the full potential of the camera. 


In comparison to them, DSLR and system cameras have very large sensors, something that is clearly evident from the image quality. The most important advantages of DSLR and system cameras are summarised below:  

For Zeiss slit lamps and surgical microscopes (OPMI), Zeiss itself offers original beam splitter modules

  Zeiss Spaltlampe Interface   

These connections have an internal diameter of 33 mm and come with a cap nut for attaching the devices together.

For this connection we offer a simple, high-quality adapter solution, which is fitted directly onto the beam splitter.

This solution makes it possible to use all conventional DSLR and system cameras with the instrument (Zeiss slit lamp and OPMI). Only the camera body (without lens) is needed for the connection. The LM DSLRFOPMI adapter is the ideal solution for cameras with APS-C and four-thirds sensors. The largest possible image field is obtained without peripheral darkening (vignetting).

If, in addition to the beam splitter, a photo adapter (video adapter) is also available, there are other possible solutions. Zeiss offers this photo adapter with different focal lengths (from 85 mm to 140 mm) with a standardised C-mount connection

The C-mount connection is a standardised connection for cameras with an external diameter of 25.4 mm. Due to this industry standard it is possible to use a large number of C-mount and USB cameras. As a rule, these cameras have a very small sensor (1/2“ in most cases). However, using the LM digital adapter, DSLR and system cameras can be attached to this photo adapter with C-mount connection without any difficulty.

The adapter solution depends on the camera used and the focal length of the photo adapter. In each case, the image should be full frame and there should be no peripheral darkening. Photo adapters with integrated iris diaphragms (see arrows in the image above) deliver better image quality, as the depth of field can be increased through the iris diaphragm. 


Thanks to the development of the LM digital adapters, it is now very easy to use DSLR cameras with slit lamps and surgical microscopes (OPMI). DSLR and system cameras feature a very good price-performance ratio and are easy to operate. The possibility of transmitting high-resolution videos (HDMI) via live feed through the output port to a large HD monitor for discussion during presentations is particularly interesting. If interested, we will be pleased to assist you in selecting the optimum adapter and camera. To help you choose the camera that is best suited for your needs, we have put together a guide and a list of camera rankings with up-to-date test reports on our website.
