Front-loading the article by unpacking the acronyms:
EO = Edmund Optics, longstanding innovators in machine vision lensing
HP = High Performance
I = Denotes “instrumentation” – Streamlined mechanical designs and fixed apertures
+ = Targeted for larger 4th gen SONY Pregius sensors: 24.5MP 1.2” IMX530 and IMX540 sensors
Fixed Focal Length Lenses… ok no acronym to unpack there… but worth noting that fixed focal length lenses, with fewer moving parts, offer high performance with lower manufacturing costs. Which translates to a compelling value proposition.
With 18 members in the EO HPI+ Fixed Focal Length Lens family, it’s possible to get the optimal fit in focal length and F-stop. These industrial lenses are built for exceptional performance in demanding factory automation (FA) and machine vision environments. The locking focus and iris rings prevent accidental adjustments.
SONY Pregious sensors – once more with feeling
While not the only player in the sensor space, SONY remains one of the most innovative and respected manufacturers. They regularly succeed their own prior releases through incremental and disruptive innovation. As we write this, there are four generations of SONY Pregious sensors. The 4th generation Pregius S captures up to 4x as much light as Sony’s own highly-praised 2nd generation Pregius from just a few years ago!
24.5MP 1.2” SONY IMX530 and SONY IMX540
Consider the SONY IMX540 sensor for a moment. It’s designed in to at least 17 different camera models carried by 1stVision, across three different camera maufacturers: Allied Vision, IDS Imaging, and JAI.
At almost 25MP, with 2.74µm square pixels, yet only a 1.2″ diagonal size, it’s suited to the C-mount lens format. That’s a robust mount design that’s widely popular in machine vision, so adopters of cameras with this sensor and mount have a wide range of lenses from which to choose. That in turn offers a range of choices along the price : performance spectrum.
EO HPI+ FFL Lens Performance
Machine vision pros know that lens performance is often characterized by the optical transfer function, also called the modulation transfer function. The shape and position of the curve says a lot about lens quality and performance. It’s also useful when comparing lenses from different manufacturers – or even lenses from different product families by the same manufacturer.
Here’s the MTF curve for one of the Edmund Optics lenses:
That’s just a representative example. We’ve got the MTF curves for each lens… either on our website datasheets or on request.
