UV Neutral Density Filters (250-380nm)
Uniform Attenuation: UV Neutral Density Filters provide a uniform reduction in light intensity across the entire 250-380nm wavelength range, ensuring consistent exposure and preventing overexposure or damage to UV-sensitive sensors or samples.
Neutral Color Balance: By maintaining a neutral color balance, these filters minimize any color distortion or shift in the transmitted UV light, preserving the integrity of spectral measurements and imaging.
Versatility: Available in a range of optical densities (OD), UV Neutral Density Filters can be selected to achieve the desired level of attenuation, from slight reduction to several orders of magnitude.
High Optical Quality: Manufactured from high-quality materials such as fused silica or quartz, these filters exhibit excellent transmission characteristics and low scattering, ensuring high optical performance.
Durability: Designed for use in demanding environments, UV Neutral Density Filters are often coated with durable anti-reflection layers and can withstand exposure to UV radiation without degradation.
Applications: Spectroscopy, Imaging, UV Curing and Exposure, UV Safety, Scientific Research, etc.
UV Neutral Density Filters are optical devices specifically engineered to uniformly reduce the intensity of ultraviolet (UV) light within the 250-380nm wavelength range, without significantly altering the spectral distribution. They achieve this by absorbing a portion of the incident UV light, allowing a controlled amount to transmit through. Unlike colored glass filters, neutral density filters maintain a neutral color balance across the specified UV spectrum, ensuring minimal distortion of the transmitted light.
