The Oriel® CS260B 1/4m monochromator is a high performance, economical, and user-friendly instrument that is ideal for research applications and production environments. Each monochromator is aligned and calibrated at the factory for this fully assembled, turn-key instrument. In addition to the pre-configured monochromators, additional customization options include wavelength range, grating configurations (two or four selectable gratings), and slit type, to best fit your required application needs.

The CS260B monochromator is a redesigned and greatly improved instrument over its predecessor. By integrating a Newport motion stage, scan speed is faster, as well as higher wavelength accuracy and precision over the original models. A robust mechanical design and optical mounting configuration has increased rigidity and reproducibility. Communication protocols have been updated, greatly reducing timeout errors and improving overall speed and efficiency.
The CS260B is assembled, pre-aligned, and calibrated at the factory, so it is ready for immediate use. The diffraction gratings are installed on a grating mount and factory aligned. A micrometer slit is pre-installed at the input port and axial output port. Dual port versions include an additional slit assembly on the lateral output port. Included with each instrument are LabVIEW™ based utility software, MonoTerm low-level command software, a user’s manual, and a certificate of calibration. A DC power supply and line cords for the US and Europe are also included.
CS260B-1 UV-NIR High Resolution Quad models use four ruled gratings that have high line densities, which correspond to higher resolution- refer to our tutorial for more information. The grating efficiency curves are relative (not absolute) calculations and should only be used as a guide to approximate actual instrument performance.
CS260B-2 UV-NIR High Resolution Dual models use two ruled gratings that have high line densities, which correspond to higher resolution- refer to our tutorial for more information. The grating efficiency curves are relative (not absolute) calculations and should only be used as a guide to approximate actual instrument performance.
CS260B-3 VIS-IR models use two ruled gratings that are better suited for IR applications- refer to our tutorial for more information. The grating efficiency curves are relative (not absolute) calculations and should only be used as a guide to approximate actual instrument performance.
CS260B-Q UV-SWIR Extended Range models use four ruled gratings to provide the widest spectral range option- refer to our tutorial for more information. The grating efficiency curves are relative (not absolute) calculations and should only be used as a guide to approximate actual instrument performance.
The optical design of the Cornerstone 260B is based upon an asymmetrical in-plane version of a Czerny-Turner monochromator. Choose a dual or quad grating assembly based on the spectral range of the application. 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 and a grating turret assembly are used to select the desired wavelength and switch between diffraction gratings quickly, without sacrificing performance.
The monochromator 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. A 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.
An electronic shutter is integrated into the monochromator's housing for the many spectroscopic applications that require the use of a shutter.

Product Series Overview
Micrometer adjustable slits offer flexibility and high throughput, but are not as accurate or repeatable as fixed slits. The micrometer adjustable slit assembly is continuously variable from fully closed to 3 mm width. The narrowest practically achievable width is 4 µm. A height adjustment slide allows variation in the height from 2 to 12 mm. This type of slit is designed primarily for versatility and convenience in changing resolution and throughput.

LabVIEW based utility software is included at no extra cost with all monochromator models to control both the monochromator and filter wheel accessory. An intuitive command set is provided for those wishing to create their own programming. The Oriel MonoTERM utility is also provided for sending low-level commands to the monochromator. This is very convenient for assisting programmers in their software development efforts. The MonoTERM utility was developed in National Instruments LabVIEW. It is open source code, so it may be used to provide LabVIEW programming examples.
These monochromators are included with both USB and RS232 communication interfaces. USB cable

These instruments continue to function for many years. With proper care, they only require periodic maintenance to ensure gears are lubricated, spring tension is correct, etc. It is suggested to send the monochromator to Newport annually for recalibration, in order to meet its performance specifications. During recalibration, the instrument is thoroughly examined and routine maintenance services are performed. In addition to this service, Newport is also able to reconfigure the grating selection, slits and communication electronics if desired. Learn more about our factory monochromator services.
