Y10103 Longpass Filter
Long-pass filter blocking blue below 510 nm while passing ≥ 92 % warm yellow-to-red light from 530 – 750 nm for glare-free, colour-true output.
- Passband: 530 – 750 nm, 92 – 95 % T (± 2 % ripple)
- Cut-on (T50): ≈ 525 nm
- Edge steepness: ~15 nm (10 → 90 % transition)
- Blue blocking: < 0.3 % T below 510 nm
- Construction: Ion-assisted hard-oxide; 5 – 450 mm shapes, 0.21 – 3.8 mm thick
- Custom options: Edge tuning, ripple smoothing, 45° AOI, rapid prototyping

Y10103 keeps all violet-to-blue light out and sends a wide, flat band from
~530 nm through deep red straight to the sensor. Transmission is
essentially zero below 510 nm; by 530 nm it rockets past 92 % and rides a
92 – 95 % plateau to 750 nm with ripple held to ±2 %. Ion-assisted
coatings shrug off heat, humidity, solvents, and repeated cleaning.
KUPO offers Borofloat®, soda-lime, Schott D263 T, or Corning Eagle XG
substrates in any outline from 5 mm chips to 450 mm plates (0.21 – 3.8 mm
thick) and can ship prototypes in about two weeks.
Typical applications: warming LED fixtures, collecting
GFP/YFP/RFP fluorescence, blue-glare suppression in machine vision,
daylight LED colour balancing in photo/film, and AR/HUD combiners that
must block blue while passing green-to-red graphics.
Description
The Y10103 filter keeps all violet-to-blue light out and sends a wide, flat band from ~530 nm through the deep red straight to the sensor. Transmission is essentially zero below 510 nm; by 530 nm it rockets past 92 % and stays between 92 – 95 % all the way to 750 nm, with ripple held to ±2 %. Use it whenever you need warm, glare-free illumination or to isolate green-red fluorescence without a secondary notch.
Key advantages
-
Steep blue cutoff – ≈15 nm edge cleanly splits cool and warm colours for high contrast.
-
High, colour-neutral plateau – ≥92 % T from ~530 nm to 750 nm keeps brightness and hue consistent.
-
Deep blue blocking – <0.3 % T below 510 nm protects sensors and removes harsh LED spikes.
-
Hard-oxide durability – Ion-assisted layers shrug off heat, humidity, solvents, and repeated cleaning.
-
Format flexibility – Available on Borofloat®, soda-lime, Schott D263 T, or Corning Eagle XG glass in any outline from 5 mm to 450 mm, thickness 0.21 – 3.8 mm.
Typical applications
-
LED colour-tuning – Warm up cool white or RGB fixtures by filtering out the blue spike without gels.
-
Fluorescence emission – Collect GFP/YFP/RFP signals while blocking blue excitation lines.
-
Machine vision – Suppress specular blue glare on shiny parts while keeping red and green channels bright for inspection.
-
Photography & cinema – Balance daylight LEDs toward a tungsten look; maintain high transmission for efficient lighting.
-
AR / HUD combiners – Inject green-to-red graphics cleanly, with zero blue leak reaching the viewer’s eye.
