Achromatic two-component focusing adapter DA-30 and DA-30-OUT
The DA-30 is an achromatic adapter consisting of two LA-30 objectives, designed to minimize spherical and chromatic aberrations. Each objective contains acromatic lenses, optimized for the UV spectral range. The adapter is equipped with an interchangeable SMA-905/FC fiber connector.
The DA-30 adapter collects radiation from an object located 77 mm from the adapter housing and focuses the radiation into an optical fiber.
In the DA-30-OUT modification, the adapter can be fixed to the monochromator's exit slit to focus the output radiation at a distance of 77 mm from the housing (the last surface of the system).
It should be noted that two-component objectives have limited chromatic aberration compensation capabilities. When operating in a broad spectral range including UV and IR, it is recommended to use mirror optics.
