The LBTEK infinite correction tube lens is designed to be used in conjunction with infinity-corrected objectives to construct an infinity-corrected optical system. To minimize losses caused by surface reflections, all lens surfaces in the infinite correction tube lens are coated with broadband anti-reflection coatings. The coating wavelength ranges are: 400-750 nm, 700-1100 nm. The infinite correction tube lens delivers diffraction-limited optical performance within the working wavelength range. During use, the M38×0.5 or SM2 threaded end should face the objective.
Key Features
- Focal length: 200 mm
- Ø22 mm imaging field of view
- Compatible with infinity-corrected objectives from major manufacturers
