Product Family Description

Ideal for Life Science Instrumentation
High Transmission, Deep Blocking
Used to Prevent Photobleaching in Microscopy Applications
Hard Coated OD 4.0 5nm, 10nm and 50nm Bandpass Filters also Available

TECHSPEC® Hard Coated OD 4.0 25nm Bandpass Filters are designed to be a midrange alternative to broadband or narrowband filters. TECHSPEC Hard Coated OD 4.0 25nm Bandpass Filters are ideal for single photon microscopy, or for preventing photobleaching of live samples or fluorophores in a range of life science applications. These filters can also be used to eliminate unwanted background noise while enhancing the signal to noise ratio in imaging or machine vision applications.

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.

All mounted TECHSPEC® Optical Filters have an arrow on the side of the mount that points to the filter-coated surface for quick reference. Filter oriented such that arrow points to filter coated surface S1. Anti-reflective (AR) coating is applied to S2.
