New! Oriel® Apex Sources with a Rear Reflector are now available. Potentially up to 60 % throughput improvement can be achieved as a portion of the backwards emitted radiation is captured to the output.
The Oriel Apex Infrared Sources operate our 9 to 24 W infrared elements. These systems are completely contained - all the electronics, infrared source and condensing lens assembly are built into the enclosure. We designed these systems with simplicity and economy in mind. By integrating all the components, we were able to keep costs down and simplify operation, with some compromise in flexibility.
No Adjustments Necessary
These systems are truly plug-and-play. The electronics are factory pre-set to operate the specified element, so you don't need to adjust the current. You don't even need to align the infrared element. Simply install the element, turn on the power, and begin your work. For those Researchers who wish to retain some flexibility, we also offer systems based on the popular Series Q Lamp Housings, which allow you to interchange elements and condensing lens assemblies.
Zinc Selenide Condenser
The output of our Apex Sources is a collimated, 1.3-inch (33 mm) diameter beam. The condenser is an F/2 Zinc Selenide assembly; ZnSe transmits from 0.6 to 12 µm. Our infrared elements have a broader range - 1 to 25 µm. The output flange of Apex is a 1.5-Inch Series female flange. Any 1.5-Inch Series male-flanged accessory mates directly to the output of Apex.

Mounting
Apex Housings have four leveling feet for free standing use. The feet allow 0.50-inch (13 mm) height adjustment. For hard mounting to an optical table, remove the feet and use the appropriate mounting holes.

* The lens multiplication factor is a measured parameter for the lens. It helps in computing the approximate total power of the collimated output in any wavelength band. Refer to our tutorial on
Calculating Output Powerfor formulae and sample calculations to compute the approximate total power from your source.
