Description
The
simple high speed optical tunable filter has a micro concave
polycarbonate lens that foams a cavity without guiding optics or
optical collimation, resulting in robust and vibration-resistant
filters with minimal parts count. The filters are encapsulated in a
proprietary temperature tuned package.
