TECHNICAL SUPPORT

Technical support and downloads

Datasheets, dimensional drawings, optical curves and selection FAQ are collected here: browse by series or download a PDF by model. If the available data is not enough for your evaluation, send the camera model, working distance and field of view, and our application engineers will recommend focal length, depth of field and mount.

FAQ

Selection FAQ

Eight questions our engineers meet most often in projects. Click a title to expand the answer.

How do I calculate the focal length of an industrial lens?

The usual estimate is: focal length ≈ sensor size × working distance ÷ field of view. For example, with a 1/1.8" sensor 7.2 mm wide, a working distance of 300 mm and a required field of view of 120 mm, the focal length is about 18 mm, so choose between 16 mm and 20 mm and verify with real image quality.

Practical selection must also consider depth of field, installation space and MOD; we recommend reserving 10%–20% of field-of-view margin.

How do I match lens image circle to camera sensor?

The maximum image circle of the lens must be equal to or larger than the camera sensor diagonal. Typical diagonals are: 1/3" ≈ 6 mm, 1/2" ≈ 8 mm, 2/3" ≈ 11 mm, 1" ≈ 16 mm, 4/3" ≈ 21.6 mm. A 2/3" camera should therefore use a lens rated for 2/3" or larger; pairing a 1/1.8" lens with a 1" camera causes corner shading and vignetting, and edge resolution drops noticeably.

What is the difference between C mount and CS mount?

C mount has a flange distance of 17.526 mm and CS mount 12.5 mm. A C-mount lens can be used on a CS-mount camera with a 5 mm adapter ring, but a CS-mount lens cannot focus on a C-mount camera. With an adapter ring the back focal length becomes shorter, so also check that the front of the lens will not hit the object or the light source structure.

How should I balance working distance and depth of field?

The closer the working distance and the longer the focal length, the shallower the depth of field. If the object has height variation or vibration, stop down the aperture or choose a shorter focal length and reserve depth-of-field margin; as a rule of thumb, each aperture stop adds roughly 40% depth of field but reduces light throughput, so balance it against exposure time. For high-precision measurement, prioritise resolution and low distortion, then control depth of field through structural rigidity and a fixed working distance.

How do motorized zoom lenses connect to a control system?

Can SWIR lenses be used with visible-light cameras?

Can I request evaluation samples?

Samples of standard models are available; please include the camera model, working distance and project schedule in the inquiry form. Samples are normally used for complete-system imaging validation and light source matching, with the evaluation period confirmed against the project plan. If you need to compare several lenses or require on-site commissioning, state the number of stations and mounting method. After testing you can move directly into procurement.

What are the MOQ and lead time for custom lenses?

Custom requirements vary widely: mount or coating adjustments have a relatively low MOQ, while a completely new optical design requires evaluation of development effort and annual volume. Common customisations include mount changes (C / M42 / F), coating waveband adjustment, barrel length and locking structure, and adding motorised iris or zoom drive. MOQ and lead time are confirmed in a formal quotation after requirement review.
