Test equipment and software
We built our own test equipment and software to verify and qualify our lenses. The same equipment is available to you, to buy or to hire.
The range covers collimators, MTF measurement, interferometry, image resolution measurement, and measurement of back focal length (BFL), effective focal length (EFL) and other optical parameters.
MTF bench
- Quick and easy set-up.
- Measures the point spread function (PSF).
- Measures and records MTF.
- Calculates lens EFL.
Collimators: three models
| Model | EFL | Aperture | Suited to |
|---|---|---|---|
| 1500 × 300 | 1,500 mm | 300 mm | Large catadioptric systems, and co-alignment of dual-lens systems up to 100 mm aperture |
| 1000 × 120 | 1,000 mm | 120 mm | Lenses of 50 to 300 mm focal length with 10 to 100 mm apertures |
| 500 × 60 | 500 mm | 60 mm | Small lenses of 15 to 100 mm focal length with 10 to 50 mm apertures |
Need to test a lens you already have?
We can test it for you, or set you up with the equipment and software to do it yourself.
