35-885 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 250nm
The 35-885 is a 50 mm diameter Bandpass Filter, designed and manufactured by Edmund Optics. This filter is specifically engineered to transmit light within a narrow band of wavelengths, centered at 250nm, while effectively blocking unwanted light outside this range. The filter features a hard coating on both the front and back surfaces, enhancing its durability and resistance to scratches and other forms of damage.
The filter's physical dimensions include a diameter of 50mm and a thickness of 3.5mm, making it suitable for a wide range of optical applications. The cut-on wavelength is 245nm, and the cut-off wavelength is 255nm, further emphasizing its precision and selectivity in light transmission. The CWL, or Central Wavelength, is 250nm, indicating the peak transmission wavelength of the filter.
The 35-885 filter is designed with a Thin Lens shape, which can be beneficial in certain optical systems. The front and back coatings are identical, both being EDM 35-871, which likely contributes to the filter's overall performance and durability.
