Dichroic Long-Pass Filter
Filters
A dichroic edge filter that transmits longer wavelengths and reflects or blocks the short-wave band, quoted from the spectrum and AOI.
Typical values
| Parameter | Reference |
|---|---|
| Reference cut-on | 500 / 550 / 600 nm examples |
| Transmission band | Long-wave side; per drawing |
| Blocking band | Short-wave side; per drawing |
| Reference AOI | 0–45° |
| Reference diameter | 12.7 / 25.4 mm |
| Substrate | Fused silica or glass |
This is a drawing-led item. The reference values below help frame the discussion; the pattern, groove or spectral data on your drawing controls the quotation.
Long-pass dichroic filters are used to separate excitation and emission bands or to protect a system from short-wave light. The cut-on slope, transmission band, blocking range and AOI are coupled. Send the full spectrum and the intended mounting angle.
