Hard-coated bandpass for 532 nm laser line cleanup, 25.0 mm mounted
| Parameter | Conditions | Min | Typ | Max | Unit |
|---|---|---|---|---|---|
| Center wavelength | AOI 0°, 23 °C | 531.0 | 532.0 | 533.0 | nm |
| Bandwidth, FWHM | AOI 0° | 2.6 | 3.0 | 3.4 | nm |
| Peak transmission | at center, AOI 0° | 85 | 90 | % | |
| Blocking | 400 to 1100 nm, outside ±10 nm | 5.0 | 6.0 | OD | |
| Shift with angle | AOI 10°, n* 2.0 | −2.01 | nm | ||
| Clear aperture | 21.0 | mm | |||
| Diameter | 24.9 | 25.0 | 25.1 | mm |
All values at 23 °C with a collimated, unpolarized beam unless stated.
Center wavelength against angle of incidence for effective index 1.45 to 2.00. Tilt shifts the band to shorter wavelengths.

Test conditions, limits and selection criteria
The datasheet states test conditions, separates typical values from minimum and maximum limits, and includes curves, a drawing and a part-number key.
The product page answers technical questions before a request for quote.
The selection guide explains which parts meet the buyer’s requirements.
Line chart. Angle of incidence (°) from 0 to 60. n_eff 1.45: 1.000 to 0.802; n_eff 1.85: 1.000 to 0.884; n_eff 2.00: 1.000 to 0.901 (Center wavelength ratio λθ / λ0).

Thin-film transmission and reflectance
Pick a stack, tilt it, and watch the reflectance curve and the color of the coating move. Every point is a transfer-matrix calculation running in your browser, the same method behind the curves on a filter datasheet.

Fused silica substrate
A single cavity with no blocking stack. Outside the mirrors' stop band it passes light again, and that leak sets most of the transmitted color.
Indices: fused silica, Malitson (1965); MgF₂, Dodge (1984); TiO₂, DeVore (1951), bulk rutile, so evaporated films run lower; Ta₂O₅, Rodríguez-de Marcos et al. (2016); N-BK7, the SCHOTT catalog.
At 13.5 nm the same calculation matches the Mo/Si mirror model on the EUV and DUV optics page to nine decimal places.

Specification review
From your measured data. I work from your test data and drawings.
Your engineers own the numbers. I don’t generate, certify or guarantee specifications; your engineers sign off every value.
Gaps go to you as a list. A missing condition or a unit that doesn’t match is flagged for your engineers, not filled in.
Product-page content. I write the copy, tables and FAQ; your web person builds the page from my notes.
Common questions
Can you start from our current datasheet?
Yes. Send the current PDF and the data behind its curves.
Do you need our raw test data?
To redraw curves, yes: the data behind each curve, under NDA if you like. For a copy-only refresh, the current datasheet is enough.
Can you use our template?
Yes. Or I set up a clean template you can reuse for the rest of the family.
Will you change our specifications?
No. I make the conditions and limits clear; your engineers decide every value.
