SCF4 controller supports majority lenses with stepper motors. 3 independent optical axes and Day/Night switch can be manipulated independently and simultaneously.
Instead of conventional X/Y/Z axis names they are renamed to A/B/C. Evaluation board has axes assigned as listed below.
L012 is 2.8-12mm Zoom/Focus and optional P-Iris lens with no reference points designed for D14-mount cameras. With D14 to CS adapter, any CS-mount camera can accept this lens without need of further modifications.
Flat Flex Cable (FFC) wire definitions and dimensions described below.
| Feature | Zoom | Focus | P-Iris |
|---|---|---|---|
| Full motion range [Steps] | 1352 | 3318 | 92 |
| Coil resistance [Ohm] | 21 | 21 | 28.5 |
| Operation voltage [V] | 3.5 ~ 5 | 3.5 ~ 5 | 2.6 ~ 3.8 |
| Operation frequency [pps] | 200 ~ 800 | 200 ~ 800 | 200 ~ 800 |
L051 5.35-96.3mm Zoom/Focus/P-Iris lens with day/night filter switch is designed for direct PCB mount.
After referencing Zoom and Focus axes and using this information along with in advance calibrated presets precise lens re-configuration is possible without the need to perform auto-focus. This drastically increases the field of view change time and accuracy in complicated situations like low light, vibrations, low contrast or fast-moving scene.
Simple DIY lightweight lens / controller / camera stack can form camera block. Parts can be printed with ordinary 3D printer or machined from more durable material.
| Feature | Zoom | Focus | P-Iris |
|---|---|---|---|
| Coil resistance [Ohm] | 55 | 55 | 55 |
| Max frequency [pps] | 1200 | 1200 | 1200 |
| Operation voltage [V] | 5 | 5 | 5 |
| Step angle °deg | 18 | 18 | 18 |
Manufacturer part number: RPI-222 ROHM
Optional lens filter switch is also called: IRC (Infra Red Cut) and D/N (Day / Night). Usually cut off wave length is 650nm.
| Feature | D/N filter |
|---|---|
| Coil resistance [Ohm] | 25 |
| Operation voltage [V] | 3.6 ~ 5 |
| Rated current [mA] | 144 ~ 200 |
| Time of application [ms] | 200 ~ 500 |
