87-801 50 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 525nm
The 87-801 is a Bandpass Filter, specifically designed with a 525nm central wavelength, sourced from the reputable vendor, Edmund Optics. This filter is circular in shape, with a 50mm diameter and a thickness of 3.5mm, making it suitable for a wide range of optical applications.
The filter is made from UVFS Mal-1965 material, a choice that enhances its performance in specific wavelength ranges. It features hard coating on both the front and back surfaces, denoted as EDM 87-777, which adds to its durability and overall optical efficiency.
The 87-801 Bandpass Filter has precise cut-on and cut-off wavelengths, set at 512.5nm and 537.5nm respectively. This specificity is crucial in applications where controlling the transmission of light is paramount. The Cut-On Wavelength (COW) is the wavelength at which the filter starts to transmit light, while the Cut-Off Wavelength (COF) is the wavelength at which the filter stops transmitting light. The Central Wavelength (CWL) is the average of the COW and COF, and in this case, it is 525nm.
The filter's geometry and physical data make it a versatile component in various optical systems. It is designed in the form of a Thin Lens, which is beneficial in applications where minimizing optical aberrations is a priority.
