Our line of TECHSPEC® Adjustable ReflX™ Objectives, formerly known as the Beck/Ealing reflecting objectives, offer a robust design and wide variety of magnifications to suit a wide range of applications. All units are configured for 160mm tube length and 0.17mm cover glass during assembly and precision aligned for optimum performance. However, to indefinitely extend the useful life of the objective, all but the 15X, 0.5NA feature the ability to adjust the centration of the internal mirrors with the provided Allen wrenches (detailed instructions included). Higher magnifications (36X, 52X and 74X) allow for adjustments to the tube length and the cover glass correction through the means of a moving collar (centration of mirrors should be checked and adjusted if tube length is changed).
Each objective is available with any of three coating options: Aluminum with a magnesium fluoride overcoat for the NUV-Visible, DUV Enhanced Aluminum for the DUV-NUV and Gold for the IR. Free from the problems of chromatic aberration and material absorption associated with standard microscope objectives, these components are ideal for applications requiring high throughput and excellent resolution, including FTIR spectroscopy and microscopy, photolithography, thin film measurement, semiconductor inspection, and laser etching.
