R.J. Wilson, Inc. offers a wide range of standard lenses for area array and line-scan cameras. With the large variety of camera sensor types, pixel sizes, and other sensor parameters, selecting the proper lens will maximize the performance of the camera, and thus the vision system, by doing a better job resolving image details with the highest contrast. The lens is generally the “gatekeeper” in terms of the camera being able to make full use of its resolution and pixel size.
Let us assist you in selecting the appropriate lens by considering the field-of-view requirements, the working distance based on your working envelope, and the resolving capability of the lens to match the camera’s resolution, sensor model and size, mounting, and pixel size specifications. We offer the top brands to help you specify the ideal lens configuration for your project.
Lenses are available for visible light imaging, ultra-violet imaging, near-infrared, and medium-range infrared applications.
When developing new camera sensors, manufacturers know that the lens used is the most significant factor in getting top camera performance. Tamron has been around for decades and a is a key partner of Sony, who is the 2nd largest shareholder in Tamron. When Sony develops a new camera sensor, they count on Tamron to develop lenses tuned specifically for the new camera sensors.
Tamron has introduced the MA111F, a 1.1-inch format lens series that supports pixel sizes down to 2.5µm. When Sony introduced its latest 1.1-inch format sensors with 2.74µm pixels, it looked to Tamron to develop a suitable lens that takes advantage of the sensor’s pixel resolution.
The MA111F Series includes 16mm, 25mm, 35mm, and 50mm models, all with M40.5 P=0.5mm filter threads and lock screws. A newly designed mechanism improves anti-vibration and anti-shock performance.
These lenses are compatible with sensors such as the Sony IMX253 and IMX304 (1.1” 12MP), IMX532 and IMX542 (1.1” 16MP), IMX531 and IMX541 (1.1” 20MP), and smaller camera sensors.

Tamron has upgraded its 2/3-inch format lenses to support 2.74µm pixels. The MA23F lenses include 8mm, 12mm, 16mm, 25mm, 35mm, and 50mm focal lengths. All but the 8mm use an M27 filter thread. The 8mm lens uses an M34 thread.
These lenses are compatible with sensors such as the Sony IMX536, IMX546, and IMX566 (2/3” 8MP) and smaller camera sensors.

As applications emerge that require a single camera to acquire images using multiple wavelengths of light, remember that focus-shift causes different wavelengths of light to focus at slightly different image planes.
The use of multiple wavelengths with a single camera and lens often results in a compromise; either one of the wavelengths is fully focused and the others are not or none of the images are fully in focus.
Tamron has introduced the SMA11 lens series to maintain improved focus over a wider range of visible and SWIR wavelengths between 400nm and 1,700nm. The SMA11 series VIS-SWIR lenses support 5µm pixels.

The newest camera sensors feature pixels as small as 2.4µm, so it’s important to use a lens that provides the resolving power to maximize camera performance when analyzing small features. The new Tamron M117FM series is a 1/1.7” format 6-megapixel rated lens. These lenses are compatible with sensors such as the new Sony IMX537, IMX547, and the IMX567 (1/1.8” 5MP, 2.74µm pixels) and the IMX178 (1/1.8”, 6MP, 2.4µm pixels), as well as smaller camera sensors.
The M117FM Series lenses are available from 6mm to 50mm and feature a newly-designed anti-vibration construction method to limit optical deflection to within 10µm, while withstanding vibrations up to 10G. These lenses provide a high-value combination of cost and performance.

One of the challenges with using large format image sensors is finding appropriate lenses that support both the larger sensor size and smaller image pixels. The lens is the gatekeeper to maximizing camera performance and the VS-HX Series delivers.
The VS-HX lenses support a large image circle of 32mm and pixels as small as 2.74um.
Focal lengths of 35mm, 50mm, and 75mm are available, featuring compact design and light weight (approx. 500g or less). Advanced design results in less distortion and flare for improved image quality.
The standard lens mount is M52, with mounting adapters available for F-Mount, TFL-Mount, and M42/FB12 cameras.
These work-horse lenses are designed for improved focusing and reduced distortion in the periphery of the image. This increases read rates for 1D and 2D barcodes that may be randomly presented throughout the image.
Fujinon’s CF–ZA-1S Series of lenses supports the larger 1.1” sensor format and pixel sizes down to 2.5µm. These lenses have been designed to provide improved relative illumination and clarity from the image center to the periphery.
Lens performance is especially critical when imaging with smaller sensor pixels. The small chief ray angle ensures that the light rays reach the pixels to provide clear and bright images across the camera sensor.
The CF-ZA lenses have been designed for ruggedness, with unique, patented anti-vibration construction to perform under the harshest industrial conditions. Please view the Fujinon video for more information on this.

Moritex lenses are well-known for high image quality in machine vision applications. In addition to maintaining focus and contrast across the field-of-view, these factory automation lenses were developed to support today’s smaller sensors and smaller pixel sizes. The smaller an image pixel gets, the more important it is to use a lens that is properly matched to the camera sensor’s parameters.
As smaller pixel sizes expose the resolving limits of many industrial lenses, Moritex lenses have the 200lp/mm performance required to make the most of camera pixels in the 2.2µm size range.
