Longwave pass or short wave pass filters made for your application
Optical Edge Filters
Delta Optical Thin Film’s Homogeneous Edge Filters feature high transmission band and steep edges. Edge filters are divided into:
- LP – Long-Wave Pass
- SP – Short-Wave Pass
Delta Optical Thin Film’s edge filters are all coated using our Ultra-Hard-Coating technology. Below you find examples of Edge Filters we have designed and coated. The data sheets show typical measured transmission curves for unpolarized light at AOI =0°.
