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.
Plano-Convex lenses are the best choice for focusing parallel rays of light to a single point. They can be used to focus, collect and collimate light. The asymmetry of this lens shape minimizes spherical aberration in situations where the object and image are located at unequal distance from the lens. The optimum case is where the object is placed at infinity with parallel rays entering lens and the final image is a focused point.
Our single layer Magnesium Fluoride AR coating is a common choice that offers an extremely broad visible wavelength range at a reasonable price. Compared to the uncoated surface, the MgF2coating provides a significant improvement by reducing the reflectance to less than 1.5%. It works extremely well from 400-700 nm and at angles of incidence less than 15 degrees.
Standard effective focal lengths provide a systematic approach allowing for lenses of different sizes to be interchanged without requiring other changes to your optical system.
These lenses have been tested for dangerous substances like Pb, Cd, Hg, Hex-Cr, PBB, and PBDE and have been found to be in compliance with RoHS allowable levels.
