Product Family Description

  • Variety of UV, VIS, and NIR Laser Lines Available
  • Deep Blocking and High Transmission
  • Steep Transmission and Rejection Slopes
  • Hard Coated OD 4.0 10nm, 25nm and 50nm Bandpass Filters Also Available

TECHSPEC® Hard Coated OD 4.0 5nm Bandpass Filters offer high transmission over a narrow spectral bandwidth at a variety of common laser lines. The narrow 5nm Full-Width Half Max (FWHM) is ideal for laser line clean-up applications, allowing for an improved signal-to-noise ratio compared to those achievable with wider band filters. TECHSPEC Hard Coated OD 4.0 5nm Bandpass Filters feature durable hard coatings to minimize filter degradation, while increasing transmission. These optical filters offer steep slopes with deep blocking to achieve high performance in demanding applications.

Note: These filters are not regulalry tested for Laser Damage Threshold (LDT). A typical energy density limit is >2 J/cm2 @ 1064nm, 20ns. Please contact us if you require a filter with a specified LDT 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.
