FSQ-OD30 50.8 x 50.8 mm Absorptive Neutral Density Filter 400-900nm

The FSQ-OD30 is a high-quality Neutral Density Filter, measuring 50.8 x 50.8 mm, designed for use in the 400-900nm wavelength range. This filter is sourced from the reputable vendor, MKS/Newport, and is available for purchase through their website. The catalog number for this product is FSQ-OD30.

This filter is a type of Neutral Density Filter, which is known for its ability to reduce the intensity of all wavelengths of light equally, without altering the color balance. This makes it an ideal choice for a wide range of applications where light intensity needs to be controlled.

The filter is rectangular in shape, a common design for Neutral Density Filters due to its versatility and ease of use. It is made from UVFS Mal-1965, a material known for its optical clarity and durability.

The FSQ-OD30 has a thickness of 3mm, providing excellent stability and resistance to damage. The front and back of the filter are coated with the New OD30 coating, which enhances its light absorption capabilities and further protects the filter from potential damage.

The filter's geometry is that of a Thin Lens, a design that minimizes optical aberrations and ensures the highest quality of light transmission. This makes the FSQ-OD30 an excellent choice for precision optical applications.
