While ArduCam does sell lenses, their website makes it very difficult to search by mount, FOV, and IR cut/passthru.
I’ve been using UCTronics - which happens to be an ArduCam supplier/reseller:
@edward - If I get access to update ArduCam’s Wiki, I’ll update the following info there.
C - Fixed focus, 1" diameter w/ 32 threads/in
CS - Same as C except focusable
M12 - 12mm diameter; on older mounts/lenses, threading is not standardized
S or M12S - Same as M12, except standard threading: 0.5 mm pitch
Field of View (FOV)
May be provided as horizontal (HFOV), vertical (VFOV), or diagonal (DFOV or just FOV).
The FOV will depend on the sensor size, pixel pitch/resolution, and focal length/distance - as well as the lens.
Here’s a FOV calculator:
They also sell lenses, but apparently only visible light, not NIR-Pass/Noir lenses.
Approximations for M12 lenses:
> 100.4H 77.3V 110.5D Wide ~15mm 54.4H 37.8V 63.4D Normal ~35mm < 36.2H 24.6V 42.9D Zoom ~55mm
Most lenses are assumed to be visible light only; IR is filtered/cut/blocked. Most sensors are sensitive to IR, even though our eyes are not - so if you are not filtering IR, your images will be tinted red and possibly a little washed out.
If you need to capture NIR (Near IR, as opposed to thermal), you need a lens that passes NIR frequencies: 750 to 2500 nm.
If you are doing night capture, you will likely need a NIR lamp. Some camera SKUs come with a pair of NIR lamps:
You can also purchase such lamps separately:
Note: despite being invisible to the human eye, such IR lamps need to be rated human safe. If using an IR led-laser (with defractor - as opposed to a diffused lamp), it needs to be rated Class 1 to be safe.
If you need to record in daylight and at night, you’ll need a switchable IR-Cut filter:
B003504 OV5647 (105deg H-FOV)
B003507 OV5647 (140deg H-FOV)
B0154 IMX219 (100-150deg FOV)
B0270 IMX477 (C-Mount 65deg FOV)
Some SKUs come with a photo-resistor that automatically enables/disables IR filtering based on ambient light. The photo-resistor can be disconnected, and DGND/IR pins can be connected to ground and an available GPIO pin (ArduCam recommends GPIO4 pin 7). See my notes at:
ArduCam indicates that they do NOT support cameras with switchable IR-Cut filters in their Multi-Camera Adaptors.
I’ve confirmed that while the following cameras do work on RPI OS and Ubuntu on Raspberry Pi4B, they do not work with ArduCam’s Multi-Camera Adaptors:
ArduCam B0424 IMX290
ArduCam B0425 IMX327
ArduCam B0423 IMX462
It appears that they simply need to update their driver, but will only do so for bulk orders.
While they’ve said they don’t support B003504 OV5647 on their multi-camera adaptors, they do support the OV5647; I’ve just ordered a pair of B003504 cameras to test this out.
If you are doing structured light depth sensing, you’ll need a Class 1 led-laser and a high resolution random point defractor, rather than an IR lamp. These are difficult to find and often expensive.
I will post a separate topic on multi-camera IR setup, and possibly a post on structured light capture in the future.
