Spherical plano concave lenses of fused silica are mostly used for UV monochromatic lights. Fused silica has almost same performance of transmittance with BK7 in visual and near IR, but has higher performance than BK7 in UV.
These lenses are useful when parallel beams are converged or lights from point sources are converted to parallel beams, namely at infinite conjugate ratios.
Non-coated and AR coated products are available as well.

NOTES! |
|
|
The edge thicknesses fare theoretical values not including chamfer. |
|
Be sure to wear laser safety goggles when checking optical path and adjusting optical axis. |
