Machine Vision Illuminators feature fan-free design.

Press Release Summary:

Series DOAL-50 V2 diffuse-on-axis, LED-based illuminators are available in red or white models with 12 or 24 V continuous and 24 V strobed power. Units are fan-free, allowing them to be used in environments, such as clean rooms, where airflow disruptions are not allowed. Anti-reflective cover protects optics from contamination and accidental damage. DOAL units are suited for applications that have flat specular surfaces requiring uniform lighting.

Original Press Release:

DOAL's Increased Performance Solves More Applications

...Up to twice the intensity of previous DOALs
...Fan-free design is quiet, reliable and clean room compatible
...Wide Choice of Color Spectrums

RVSI/NER, designers and manufacturers of NERLITE® Machine Vision Illumination products, is pleased to announce the new DOAL-50 "V2" (Version 2) Series of high-output, diffuse on-axis, LED based machine vision illuminators.

The DOAL-50 "V2" series offers the performance, features and options needed to assure broad application coverage:
o Light intensity has been doubled over that of previous DOALs (red LED models; others tbd)
o Fan-free design results in a quieter, more reliable unit suitable for environments where airflow disruptions are not allowed (e.g. clean rooms) and where air born dust penetration threatens the life of fan cooled devices
o Available with anti-reflective cover to protect optics from contaminants and accidental damage
o Available in red (630 nm) or white (6500 Kelvin) LED standard models (blue, green, IR, UV or other wavelengths available on request)
o Standard models available with 12 or 24 volt continuous and 24 volt strobed power
o 24 volt continuous "Flying Leads" power option simplifies integration in systems with 24 volt power taps for peripherals
o Strobe models support optional SAM-D Strobe Adapter (DVT p/n IN00-STROBE) for use with DVT Systems

The DOAL is designed for applications that have flat specular surfaces requiring uniform lighting. With the DOAL, light rays travel on the axis formed between the object and the camera's lens. Reflecting off a beam splitter in the DOAL's aperture, light rays are directed on to the object at nearly 90°. This lighting technique helps bring out surface textures, elevation changes and translucent features. As with all NERLITE products, DOALs feature fasteners that are installed to specific torques and thread-locked so as not to loosen when subjected to the vibrations common to many applications.

DOAL-50 "V2" Series products are available now from RVSI/NER distributors worldwide.
