Product Family Description

  • Ideal for Life Sciences or Chemical Analysis
  • Available in UV, VIS, and IR Center Wavelengths
  • Feature High Performance Hard Coatings
  • Hard Coated OD 4.0 5nm25nm, and 50nm Bandpass Filters Also Available

TECHSPEC® Hard Coated OD 4.0 10nm Bandpass Filters are narrowband filters used extensively in applications including flame photometry, elemental or laser line separation, fluorescence, laser diode cleanup, or chemical detection or analysis. These optical filters offer steep slopes with deep blocking to achieve high performance in demanding applications. TECHSPEC Hard Coated OD 4.0 10nm Bandpass Filters feature durable hard coatings to minimize filter degradation while increasing transmission. The bandpass filters are available in UV, VIS, and IR center wavelengths. 

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.
