( Brand: Thorlabs ), ( Part Type: Filter Case ), ( Manufacturer Part Number: NE03B-A )
The Thorlabs NE03B-A 25mm Neutral Density Filter is a high-quality optical filter designed to reduce the amount of light entering an imaging system without affecting the color balance. This filter is part of Thorlabs' N-BK7 series, which is known for its superior optical quality and durability.
The NE03B-A filter features a 25mm diameter and is made of BK7 glass, which has a refractive index that is close to that of crown glass and a low dispersion rate. This makes it an excellent choice for applications where color fidelity is crucial.
The filter has a neutral density value of 0.3, which translates to a 1-stop reduction in light. This can be particularly useful in various imaging applications, such as photometry, time-lapse photography, and astronomy, where controlling the amount of light is essential.
The NE03B-A filter is coated with Thorlabs' proprietary NB Coating, which is a broadband neutral density coating that provides excellent optical flatness and consistency across the visible spectrum. This coating ensures that the filter has minimal absorption in the visible range, preserving the color balance of the image or signal.
The filter is also scratch-resistant, making it a reliable choice for use in demanding environments. Its flat, parallel edges ensure that it can be easily mounted in filter holders or other imaging systems.
The Thorlabs NE03B-A 25mm Neutral Density Filter is an ideal solution for anyone looking to reduce the amount of light entering their imaging system without compromising color balance. Its high optical quality and durability make it a valuable addition to any imaging setup.
