86-953 25 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 625nm

The 86-953 is a Bandpass Filter, specifically designed by Edmund Optics with a 25 mm diameter and a thickness of 3.5 mm. This filter is engineered to allow light transmission within a specific range of wavelengths, while blocking out unwanted light from other wavelengths.

The 86-953 filter has a center wavelength (CWL) of 625nm, which is the wavelength at which the filter has its maximum transmission. The cut-on wavelength is 600nm, and the cut-off wavelength is 650nm. This means that the filter starts to transmit light at 600nm and stops transmitting at 650nm, effectively passing light in the 50nm band centered around 625nm.

The filter is made from UVFS Mal-1965 material, and it features hard coating on both the front and back surfaces. This hard coating enhances the durability of the filter, making it resistant to scratches and other forms of damage. The filter's shape is that of a thin lens, which helps to minimize optical aberrations and distortions.

The 86-953 filter is currently in stock and available for purchase through the Edmund Optics website. It is a versatile and reliable option for applications that require precise wavelength selection, such as fluorescence microscopy, spectroscopy, and optical telecommunications.
