Turn-key monochromator comes assembled & aligned
The Oriel® CS260™ Extended Range 1/4 m monochromator is a high performance, economical and user-friendly instrument that is ideal for research and OEM applications. The two ruled gratings covering the 250 to 2400 nm spectral range are aligned at the factory in this fully assembled, turn-key instrument. Available options include slit type, number of output ports and communication interfaces.
Extended Range CS260 monochromators come with two ruled gratings that are installed and aligned on a grating mount. A high precision motor is used to select the desired wavelength and switch between diffraction gratings quickly, without sacrificing performance.
The optical design of the Cornerstone 260 is based upon an asymmetrical in-plane version of a Czerny-Turner monochromator. The optical configuration is designed to ensure high resolution and maximum throughput. This F/3.9 monochromator is optimized to provide excellent stray light rejection while minimizing aberrations. A high precision motor is used to select the desired wavelength and switch between diffraction gratings quickly, without sacrificing performance.
The CS260 is available with a single output port or dual output ports. A single output port is the most economical choice, and the simplest arrangement when using a single detector. If more than one detector is required for the application, the use of a single output port instrument results in the experiment needing to be stopped to switch detectors. An alternative is to use a beamsplitter after the output port, which results in lower power reaching the two detectors.
In this situation, a dual output port monochromator may be a better choice. Two output ports allow continuous scanning over a broad wavelength range without needing to break down the setup to swap detectors. An flip mirror inside the monochromator is used to select the output port. This mirror is controlled through the monochromator software, low level commands or the optional hand controller. Please note that with dual output port instruments, an unused port left uncoupled can become a source of stray light entering into the monochromator.
