Chromax Full Spectrum Sorting

WECO optics technology provides efficiency, reliability and performance — while saving you money.

LED Illuminator

Light Emitting Diodes (LEDs) are found in a wide variety of products today: cars, computer screens, televisions, traffic signals, home and commercial lighting, and even rifle scopes, to name just a few. The need for more efficient and longer-lasting light sources for all types of illumination tasks has driven LED advances over the past decade. LEDs today put out many times the amount of light vs. LEDs of just a few years ago. The Chromax LED illuminator uses the latest state-of-the-art LEDs for the highest possible output, reliability and efficiency.


The Chromax LED illuminator has no spinning mirrors. In fact, there are no moving parts at all. All alignments and calibrations are done at the factory and, due to the rigidity of the optic modules, they are unaffected by rough treatment during shipping and operation.


WECO Chromax sorters have very low power requirements and do not require active cooling. Fans or chillers are not necessary — even in ambient temperatures above 100oF.


All photographers know that the key to a good photograph is proper lighting. The same is true for optical sorting. The image seen by the sorting camera depends on the nature of the illumination. Unlike laser-based systems, the Chromax LED sorting optics generate horizontally diffuse illumination. This minimizes spectral reflections from shiny or wet objects, reducing potential color errors.

Full Color Spectrum

ChromaxHD sorters are full-spectrum sorters operating over the entire visible and infrared spectrums. Multiple color spaces make the sorters extremely flexible tools for performing a wide variety of sorting tasks. Modeled after human color perception, the sorter is very intuitive to set up and fine-tune in operation.

Controlled Depth of Field

While being highly diffuse horizontally, the special optics collimate the light vertically. Not only is this a very efficient use of the light generated by the LEDs, but it also allows for a controlled depth of field and excellent color calibration without requiring a background surface/roller that must be kept very clean. WECO Free-Space Optics eliminate the need for controlled backgrounds and their associated maintenance.


In the unlikely event that a Chromax optic module fails, a WECO technician replaces it on site in just a few minutes, without requiring alignment or calibration. This limits the risk of lengthy and costly downtime.
