Features

N-BK7 Substrates for VIS and NIR Applications

N-BK7 is an excellent lens material for most visible and near infrared applications. It is the most common borosilicate crown optical glass, and it provides great performance at a good value. Its high homogeneity, low bubble and inclusion content, and straightforward manufacturability make it a good choice for transmissive optics. N-BK7 is also relatively hard and shows good scratch resistance. The transmission range for BK 7 is 380 to 2100 nm. It is not recommended for temperature sensitive applications, such as precision mirrors. For more information, refer to our optical materials technical note.

Mount in Standard Lens Mounts

These round plano-convex cylindrical lenses are designed to mount into standard optical lens mounts.  The round optic shape provides many more mounting options compared to rectangular cylindrical lenses that require special cylindrical lens mounts for mounting.
