High Performance OD 4.0 Longpass Filters
From fast modifications to stock optics to custom designs, we can help you take your optical system from design to prototype to volume production. Contact us to get started today.
TECHSPEC® High Performance OD 4.0 Longpass Filters feature high transmission in the pass band combined with superior blocking in the rejection band. Due to a rejection band optical density of 4.0 combined with >91% in the pass band, these filters are ideal for a wide variety of applications. TECHSPEC® High Performance OD 4.0 Longpass Filters are hard coated, with a hard dielectric sputtered as the first surface and AR coating as the second. Eliminate stray light by creating custom bandpass filters when combined with TECHSPEC® High Performance Shortpass Filters.
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.
TECHSPEC® Rotating Filter Wheel can be used for applications requiring a variety of filters.
