NDIR30B Dia. 25 mm Unmounted IR Reflective Neutral Density Filter; OD 3.0

The NDIR30B is a circular, unmounted Neutral Density Filter with a 25 mm diameter and a thickness of 1 mm. This filter is sourced from Thorlabs, a renowned vendor in the optical industry. It is designed to uniformly reduce the intensity of incident light while maintaining the original color balance. The filter features a high Optical Density (OD) of 3.0, which translates to a 99.9% transmission reduction at the specified 5000 nm wavelength.

The NDIR30B filter is coated with Thorlabs' proprietary NDIR30A coating on both the front and back surfaces. This coating enhances the filter's performance by ensuring high transmission and low reflection across the intended wavelength range. The filter's thin lens shape further contributes to its performance by minimizing optical aberrations.

This filter is an excellent choice for applications that require precise control over light intensity, such as high-power laser systems, biomedical imaging, and machine vision systems. It is also suitable for use in infrared (IR) spectroscopy and other IR-based analytical techniques.

Please note that the NDIR30B filter is unmounted, meaning it does not come with a mounting mechanism. Users may need to source or fabricate a suitable mount for their specific application.
