How do I calculate the image circle needed for my line scan sensor?

Required image circle must be at least the sensor line length: line pixels x pixel pitch. Example: 8192 pixels x 5 um = 40.96 mm, which the 46 mm image circle of the EK series covers with alignment margin. Always add margin for sensor seating tolerance before locking the choice.

When should I choose a line scan camera over an area scan camera?

Choose line scan when the part moves continuously and uniformly: webs, foils, electrodes, glass panels, cylinders. The line sensor builds the image from motion, so resolution along the travel direction is set by encoder and line rate, not by a fixed pixel matrix. Choose area scan for discrete, stationary parts.

Do your 8K lenses support 5 um pixels?

Yes. The EK4032A and EK5028A are built for the 8K 5 um sensor class, with a 46 mm image circle and M42 / M58 / M72-F mount options.

Do you offer 16K line scan lenses?

Yes, 4K / 8K / 16K coverage is within our line scan range. 16K specifications are quoted per project against your sensor, because 16K line lengths demand larger image circles; send the sensor spec for a matched proposal.

Which mount do I need: M42, M58, or M72-F?

Mount follows your camera body and image-circle class: larger image circles need larger mechanically stable mounts. The EK series is offered in M42, M58, and M72-F; our team confirms mount compatibility as part of the free selection review.

Can you match lenses to SWIR line scan cameras?

SWIR sensors demand lens transmission and chromatic correction in the shortwave-infrared band, not just a bigger image circle. Send your SWIR sensor model and waveband and our engineers will assess the matched optical solution for feasibility and quote.

What should I consider for high-speed line scan cameras?

High line rates shorten exposure, so the lens aperture, illumination, and sensor sensitivity must be budgeted together. A larger image circle also makes edge illumination uniformity harder; that is exactly what our large-format aberration correction and per-batch MTF reports address.

Will these lenses work with third-party line scan cameras?

Yes. The EK series mounts in M42, M58, and M72-F, the common mounts on mainstream line scan camera platforms from vendors such as Basler, JAI, Keyence, and Cognex. Send the camera model and we confirm mount and flange compatibility.

What test reports come with an order?

Batch MTF and distortion reports, BFL / DOF data, and certificate of conformance, anchored on Trioptics-class centration and interferometer-based metrology under our ISO 9001 system.

What is the lead time and sampling policy?

Catalog lines follow standard terms; custom variants run prototype-to-mass-production in 60 working days, repeat orders in 30 days. Sampling for line validation is standard practice under NDA.

Can you match a lens to a sensor that is not on any list?

Yes. Send the sensor datasheet - pixels, pitch, line length, spectral range - and we run the coverage and MTF budget for you, usually within one business day.
