65-180 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 830nm

The 65-180 is a Bandpass Filter with a diameter of 25 mm, sourced from the reputable optical components vendor, Edmund Optics. This particular filter is designed to transmit light within a specific wavelength range, while blocking other wavelengths, making it ideal for applications that require narrowband light transmission.

The filter's central wavelength (CWL) is 830nm, which is the wavelength at which the filter has its maximum transmittance. The cut-on wavelength is 825nm, and the cut-off wavelength is 835nm. This means that the filter starts transmitting light at 825nm and stops transmitting at 835nm, effectively passing light in the 830nm range.

The 65-180 filter is hard coated on both sides with the coating type edm 65-119. This coating enhances the filter's durability and resistance to environmental factors, ensuring long-lasting performance. The filter's thickness is 3.5 mm, providing structural stability and minimizing optical distortions.

This filter is available in a Thin Lens shape, which is designed to minimize optical aberrations and distortions. The filter's geometry, including its 25 mm diameter, is optimized for use in various optical systems, providing flexibility in system design.

According to the vendor's information, this item is currently in stock, ensuring quick delivery and availability for immediate use. The filter's catalog number is 65-180, and it can be found on the Edmund Optics website for further details and specifications.
