85-886 12.5 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 1300nm
The 85-886 is a Bandpass Filter, a type of optical filter that allows only a specific range of wavelengths to pass through while blocking others. This particular model, sourced from Edmund Optics, has a diameter of 12.5 mm and a thickness of 3.5 mm, making it suitable for a variety of optical applications.
The filter is designed to operate at a central wavelength (CWL) of 1300nm, with a cut-on wavelength of 1275nm and a cut-off wavelength of 1325nm. This means it allows transmission of light primarily in the 1300nm range, contributing to improved signal-to-noise ratio in applications such as optical communication and sensing.
The 85-886 features hard coating on both the front and back surfaces, denoted as 'edm 85-886'. This coating enhances the filter's durability and resistance to environmental factors, ensuring longevity and reliability in its performance.
The filter's geometry is shaped as a thin lens, which can be beneficial in certain optical systems where minimal thickness is required. The catalog number for this item is 85-886, and it is currently in stock, according to the vendor's website.
