Product Details

OD 6.0 Rejection of Laser Wavelength from 355 to 1064 nm
Broad Transmission Range
Ideal for Laser-Based Raman, Fluorescence, and Biomedical Systems
OD 4.0 Notch Filters and OD 6.0 Multi-Notch Filter for Nd:YAG Lasers Also Available

TECHSPEC® OD 6.0 Notch Filters feature deep blocking with broad transmission bands that are ideal for use in laser analysis applications where specific wavelengths need to be blocked in order to maximize system performance. For instance, TECHSPEC® OD 6.0 Notch Filters can be used in Raman spectrometers to eliminate unwanted noise from the pump laser source to obtain the optimum signal-to-noise ratio. These optical filters feature hard coatings that will not degrade with time, temperature, or humidity, and have been mounted in black anodized rings that have been engraved to ease filter handling, identification, or orientation.

TECHSPEC OD 6.0 Notch Filters feature high OD 6.0 blocking, one of the highest optical densities for notch filters in the optics industry. High blocking at the center wavelength coupled with high transmission of wavelengths outside of this makes these notch filters ideal when high throughput is critical.

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.

Technical Information

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.
