NDIR03B Dia. 25 mm Unmounted IR Reflective Neutral Density Filter; OD 0.3
The NDIR03B is a circular, unmounted Neutral Density Filter with a diameter of 25 mm and a thickness of 1 mm. This filter is sourced from Thorlabs, a reputable vendor known for its high-quality optical components. The filter is designed to reduce the intensity of incident light without altering its color composition, making it an ideal choice for various applications involving intense light sources.
The NDIR03B filter features a front and back coating of tho ndir03a, which is Thorlabs' specific Neutral Density coating. This coating ensures consistent attenuation of light across the visible and infrared spectrum, with an Optical Density (OD) of 0.3. This OD value signifies that the filter reduces the light intensity by a factor of 2 (approximately 50% transmission).
The filter's geometry is shaped as a Thin Lens, which can be beneficial in certain optical systems where a lens-like element is required. The NDIR03B is currently in stock and available for immediate purchase through the provided weblink.
