Dichroic Coatings

Dichroic Shortpass Filters are typically optimized for a 45° angle of incidence. Light that is not transmitted is reflected at 90°, making these filters well-suited for fluorescence applications or as spectral beamsplitters. They offer low polarization dependence, wide spectral ranges, and utilize precision fused silica substrates. To enhance durability without compromising performance, hard coatings are applied. These coatings ensure that Dichroic Longpass Filters exhibit high resistance to humidity, temperature fluctuations, and abrasion, minimizing the risk of damage during handling.
