65-686 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 455nm
The 65-686 is a 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter with a thickness of 7.5 mm, specifically designed for a central wavelength of 455nm. This filter is sourced from the reputable vendor, Edmund Optics, and is available for purchase directly from their website.
This Bandpass Filter is a type of optical filter that allows only a specific range of wavelengths to pass through it while blocking others. In this case, the 65-686 is designed to permit the transmission of light within the 450nm to 460nm range, making it ideal for applications that require a narrow band of light around the 455nm wavelength.
The filter is constructed with a circular geometry, boasting a diameter of 25mm, and is crafted from the material ID UVFS MAL-1965. The UVFS MAL-1965 is a unique material that ensures the filter's durability and efficiency.
The 65-686 is coated on both the front and back with the EDM 65-626 coating. This coating enhances the filter's performance by reducing unwanted reflections and increasing transmission. The filter's shape is that of a Thin Lens, further optimizing its optical performance.
The physical data of the filter includes a cut-on wavelength of 450nm and a cut-off wavelength of 460nm. This means that the filter begins to transmit light at 450nm and stops transmitting at 460nm, effectively capturing the 455nm wavelength.
