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. These filters are ideal for fluorescence microscopy or other life science applications that rely on fluorescence detection such as flow cytometry or qPCR. 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.

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.
