These research-grade couplers provide superior image quality, low price, and excellent camera stability for mounting digital SLR and other large format sensor cameras to microscopes. A wide variety of cameras are accommodated using the industry standard camera T-mount adapter, while the bottom of the coupler ensures a solid fit to your microscope's photoport.

Wide Field of View
The 1.2x digital SLR coupler provides a wide field of view for cameras with large format sensors up to 25 mm in diagonal. The 1.2x adapter is ideal for the 4/3" format of the Olympus E series digital SLR cameras. The 2.0x version supports sensors up to 41 mm in diagonal and is ideal for the APS-C and APS-H sensors used in the Nikon DX and FX, Canon EOS Rebel, 50D, 60D, 7D, 1D Mark III, and 5D Mark II, Fujifilm Pro, Sony-Minolta Alpha, Samsung/Pentax-K, and Sigma SA and SD cameras. The APS-F sensor size is supported with the 2.0x version with a small amount of vignetting which could be cropped out of the image. Alternatively, a 2.5x PA1 adapter can be used with the APS-F sensor cameras without any vignetting. The APS-F sensor is used in the Nikon FX, Canon EOS 1Ds, and Canon 1D Mark IV. Please see our field of view diagrams for a graphical representation of this information.

Add Magnification to a System
The digital SLR couplers can also be used to provide higher magnification for cameras with 1/2", 2/3", or 1" format sensors. The digital SLR couplers add magnification from 1.8x to 8.0x depending on the sensor and adapter used.

Compatible with a Broad Range of Camera Lens Mounts
Virtually any camera can be mated to these couplers through an industry-standard "T-Mount" thread adapter. T-mounts are available for Canon EOS, Sony-Minolta, Four Thirds Olympus Mount, C-Mount, Sigma SA/SD Mounts, Nikon F-Mount and Samsung-Pentax K Bayonet Mount lens mounts, among others.

Low Profile, High Quality and Great Stability
These couplers take advantage of the removable phototube of modern microscopes to position the camera close to the microscope body, reducing vibration. Computerized lens design optimizations, years of coupler design experience, and precise manufacturing ensure crisp high contrast images.
