AND-15C-70 15 mm Dia. Optical Glass Unmounted Visible Absorptive Neutral Density Filter 400-700nm

The AND-15C-70 is a Neutral Density Filter, specifically designed for use in the visible light spectrum, with a wavelength of 550nm. This filter is manufactured by OptoSigma, a renowned vendor in the optical industry, and is available for purchase through their website. The catalog number for this product is AND-15C-70.

This filter is circular in shape, with a diameter of 15mm and a thickness of 2mm, making it suitable for a wide range of optical applications. The filter is made from UVFS MAL-1965 optical glass, a material known for its high-quality light transmission properties.

The filter features absorptive coatings on both the front and back surfaces, specifically Opt AND-70. This coating is designed to absorb a specific amount of light, reducing the intensity of the light passing through the filter without altering its color balance. This makes the filter ideal for applications where light intensity needs to be controlled, such as in photography or scientific research.

The filter has a shape described as a Thin Lens, which refers to its optical design. This shape is often used in optical systems where a flat surface would cause unwanted reflections or distortions.

According to the vendor's website, the filter is currently in stock, making it readily available for purchase and use in your optical projects.
