86-662 25 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 900nm

The 86-662 is a Bandpass Filter with a 25 mm diameter and a hard-coated OD 4.0, designed to transmit light in the 900nm wavelength range. This filter is sourced from Edmund Optics, a leading global manufacturer and supplier of optical components.

The filter is specifically designed with a 25nm bandwidth, centered at 900nm. This means it allows light to pass through if its wavelength is within the range of 887.5nm to 912.5nm, effectively blocking out other wavelengths. This feature makes it ideal for applications that require the isolation of specific wavelengths, such as in spectroscopy or laser technology.

The filter's geometry includes a diameter of 25mm and a thickness of 3.5mm, providing a robust and compact design. The hard coating on both the front and back surfaces enhances durability, making it resistant to scratches and other forms of damage.

The 86-662 filter features a thin lens shape, which is beneficial for applications that require a flat, even surface. This shape also minimizes optical aberrations, ensuring that the transmitted light is of high quality.

The filter's physical data includes a cut-on wavelength of 887.5nm and a cut-off wavelength of 912.5nm. This information is crucial for understanding the filter's performance and selecting the right component for your specific application.
