800nm Optical filter with 30nm FWHM

This precision-engineered optical bandpass filter is designed for applications in the Near-Infrared (NIR) spectrum, specifically centered around 800nm. With a Full Width at Half Maximum (FWHM) of 30nm, this filter provides selective transmission while effectively blocking wavelengths outside the specified range.

Specifications:

• Central Wavelength: 800nm
• Full Width at Half Maximum (FWHM): 30nm
• Transmission Range: Passes light between approximately 785nm and 815nm, with peak transmission at 800nm.
• Blocking Range: Significantly reduces transmission outside the 800nm ±15nm range to minimize interference and enhance the signal-to-noise ratio.
