808nm Optical Bandpass Filter with FWHM 10nm

This high-precision optical bandpass filter is engineered to transmit light centered around 808nm, with a Full Width at Half Maximum (FWHM) of 10nm. It is designed to provide exceptional wavelength isolation with narrowband transmission.

Specifications:

• Central Wavelength: 808nm
• Full Width at Half Maximum (FWHM): 10nm
• Transmission Range: Allows light to pass between approximately 803nm and 813nm, with peak transmission at 808nm.
• Blocking Range: Effectively attenuates wavelengths outside the 808nm ±5nm range to minimize interference from other wavelengths.

Features:

• High Transmission Efficiency: Optimized for maximum light throughput at the central wavelength, ensuring clear and precise optical measurements.
• Advanced Coatings: Features high-quality hard coatings to enhance performance, durability, and spectral purity.

Applications:

• Laser Applications: Ideal for use in laser systems where precise wavelength control around 808nm is required, such as in optical pumping or diode lasers.
• Spectroscopy: Suitable for spectroscopy applications that demand narrowband wavelength isolation for accurate spectral analysis.
• Imaging Systems: Enhances image quality by filtering out unwanted wavelengths, improving contrast and detail in imaging systems sensitive to 808nm.
• Biomedical Research: Useful in applications such as fluorescence microscopy where specific wavelength isolation enhances signal detection and clarity.
