TECHSPEC® Hard Coated OD 4.0 25nm Bandpass Filters are designed to be a midrange alternative to broadband or narrowband filters. These filters are ideal for single photon microscopy or for preventing photobleaching of live samples or fluorophores in a range of life science applications. TECHSPEC® Hard Coated OD 4.0 25nm Bandpass Filters can also be used to eliminate unwanted background noise while enhancing the signal-to-noise ratio in imaging or machine vision applications. The filters are designed to have a 0º angle of incidence and are mounted in a black anodized ring. Hard Coated OD 4.0 5nm, 10nm, and 50nm bandpass filters are also available.
Note: These filters are optimized for high spectral performance rather than high Laser Induced Damage Thresholds (LIDT). A typical LIDT for these filters is 1 J/cm2 @ 532nm, 10ns. Please contact us if you require a filter with a higher LIDT value.
