Coloured glass neutral density (ND) filters can suffer from uneven transmittance and fitment issues. Standard coated ND filters can struggle with reflected light. This white paper explains how HOYA’s filtration solution can address these challenges.

This white paper explains how the 1550 nm band can supplement or replace the 905 nm band in automotive LiDAR applications. HOYA offers superior filtration options for designers operating in both bands.

This white paper explains how to improve the visibility of displays in the cockpit during daytime.

Optical filters are often overlooked, but they are important or even crucial components in every optical instrument. While working at an optical filter company for almost 10 years, Pust witnessed customers’ widespread and increasing tendency to consider optical filters a commodity that only needs to be thought of at late stages during the development process of a new optical instrument. By this point, customers are often told that filters with the desired requirements cannot be designed, or that they can only be produced at prohibitive cost.

A good optical measurement almost always starts with a high-performance optical filter. Therefore, it is necessary to understand optical filters and to consider them from the beginning of the design process. It is also a good idea to involve the filter manufacturer early on, to obtain valuable insights and tips to prevent blind spots and unnecessary cost.

Pust provides a technical and market-centric overview of optical filters in 2021 and speaks to current and emerging trends, technologies, and applications.
