You're mounting this in a machine vision line where ambient IR from hot tooling is bleeding into the sensor—your camera's seeing ghost images and false edges, so what you need is something that kills visible light below 680nm cold while passing anything past 800nm with over 89% transmission.
We cut these from K9, BK7, fused silica, or float glass depending on what you're doing—thermal cycling in aerospace calls for quartz or fused silica, but for a benchtop photography rig the B270 or D263T works fine and keeps cost down. Sizes run from 3mm up to 1200mm, thickness from 1.2mm to 5mm, and the suface quailty goes 10/5 to 60/40 depending on how tight your application is (most buyers go with 20/10 for machine vision).
Teh standard spec is 400 to 680nm at less than 1% transmission, then 800 to 1600nm at better than 89%—that's a steep cutoff edge, not a gradual slope. Angle of incidence is 45 degrees, and as you tilt it the cutoff shifts toward shorter wavelengths, so if you're at steeper angles you'll need to confirm the CWL with us (our company can custom-cut the center wavelength).
What it's not great for is any application needing wide-angle acceptance past 50 degrees—the performance drops off, and you'd be better off with a bandpass or a different substrate. Also, the chamfer is standard 45 degrees by 0.2mm, but if you're mounting in a tight housing and need a different edge break, just tell us. We usually have stock on common sizes like 25mm and 50mm rounds, but confirm lead time for square blanks or custom shapes—it's about 20 days or so.
So basically, if your sensor is getting washed out by ambient IR or you're trying to block laser scatter in a protective window, this does it. The MOQ is flexible, we provide COA with HPLC or spectrophotometer data on request, and the finish is typically 10/5 for precision optics—tighter tolerance than most off-the-shelf colored glass filters.
We have ISO and SGS certifications, and we can absolutely provide test reports upon request. Just let us know what specific tests you need.
MOQ depends on the complexity and size, but for standard custom sizes and CWLs, we usually start at 10 pieces. For larger runs or special materials, we can be flexible.
Yes, exactly. At 45° angle of incidence, the standard spec is T<1% from 400 to 680nm and T>89% from 800 to 1600nm. That's for the long pass filter we offer.
We pack each filter individually with protective foam or interleaving paper, and for larger sizes we use custom wooden crates to avoid any damage during transit.
Yes, we can achieve λ/10 surface flatness and 10-5 scratch-dig on all the materials listed, including K9, BK7, Quartz, and Fused Silica. Thicker substrates help maintain that quality on larger pieces.
