Adjusting Filter Specs for Performance and Practicality

Filter designs often start with ideal specifications in mind, but not every application requires the tightest tolerances or most complex coatings. Adjusting some parameters can often lead to more efficient manufacturing and reduce cost without compromising system performance.

To give you some ideas to consider, here are a few specification areas that may offer opportunities for optimization:

Spectral specifications are a good place to start. Parameters including angle of incidence and cone-angle tolerance, blocking requirements, and edge steepness can often be relaxed depending on your light source, detector, or system requirements. Identifying where flexibility is possible can lead to better yields and shorter lead times.

Physical characteristics can also influence cost and throughput in meaningful ways. Below are some additional spec areas that may be worth reviewing:

Bulk packaging, simple shapes, commercial grade substrate materials, and looser surface quality requirements can all help streamline production, especially in non-imaging systems or high-volume builds.

Not sure what to adjust? Don’t worry. We’re here to help you find the right balance between performance and practicality. And if your specifications are already finalized, that’s fine too. We’re fully prepared to deliver to your exact requirements.
