Precision Custom IR Filters – Made for Real-World Optics

2026-07-09

When you’re building security cameras, facial recognition terminals, or automotive monitoring systems, the IR filter you choose really matters. Off-the-shelf parts might seem convenient, but they often introduce ghosting, flare, or poor transmission—issues that lead to frustrating rework and delayed product launches.

At Saida Glass, we take a different approach. We work closely with you to turn your specs into IR pass filters that actually perform. Whether you need a specific shape, a tight tolerance, or a special coating, we build it exactly the way you need it.

Our Core Capabilities at a Glance

Processing Capability	Technical Description & Benefits
Custom Sizes & Shapes	No standard templates here. We cut to your exact dimensions, including complex cutouts, holes, and non-standard geometries. Perfect for cramped or oddly shaped camera modules.
IR High-Transmission Bands	Precision optical coatings optimized for specific NIR wavelengths (e.g., 850nm, 940nm). Achieves >90% peak transmittance while deeply blocking visible light (400-700nm) to prevent daytime color cast.
AR (Anti-Reflective) Coatings	Multi-layer Ar Coating on both surfaces dramatically reduces surface reflection (<0.5%), ensuring maximum light throughput and superior low-light sensitivity.
AF (Anti-Fingerprint) Coatings	Hydrophobic and oleophobic top layer repels smudges, dust, and oils. Facilitates easy cleaning during assembly and maintains long-term optical clarity in the field.
Pre-Applied Back Glue (Adhesive)	Precision die-cut PSA (Pressure Sensitive Adhesive) tape applied to one side. Offers a “ready-to-install” drop-in solution, eliminating glue dispensing on your production line and ensuring consistent alignment.

Ghosting and flare? We solve that at the root.

Ghosting and flare are the two most common headaches in IR imaging. They happen when light bounces inside the glass or scatters at the edges. Instead of trying to fix these issues later, we design them out from the start. With carefully optimized coating stacks and proper edge treatment, we produce filters that deliver clean, high-contrast images—with no stray light to confuse your sensor.

From prototypes to full-scale production

We know that R&D teams need fast turnaround, while production lines need consistency. We’re set up for both. Need 10 samples to test? No problem. Need 100,000 pieces for a global launch? We can scale smoothly without sacrificing quality. Every order, big or small, gets the same attention to detail.

Let’s talk about your project. Share your CAD files or target wavelengths, and we’ll get back to you with a practical, cost-effective solution.
