Oriel 77200 1/4 m Monochromator

Oriel 77200 1/4 m Monochromator

Product catalog summary

Overview: The document provides detailed specifications and configurations for the Oriel 77200 1/4 m Monochromator, designed for laboratory and academic applications requiring high resolution and throughput.

Specifications: The monochromator offers a resolution of 0.1 nm with a 1200 l/mm grating and a 10 µm x 2 mm slit. It features a focal length of 250 mm, F/4.4 optics, and a usable wavelength range from 180 nm to 24 µm with interchangeable gratings. The device weighs 12 lbs (5.5 kg).

Optical Configuration: The monochromator uses an in-plane asymmetrical Czerny-Turner configuration, minimizing aberration across the working wavelength range.

Gratings: The document lists various grating models with different line densities, blaze wavelengths, and primary wavelength ranges. Gratings are prealigned in protective frames for easy handling.

Slit Assemblies: Three types of slit assemblies are available: micrometer-driven, multiple fixed, and fixed slits. The micrometer-driven slit assembly offers variable widths from 4 µm to 3 mm and adjustable heights from 1 to 15 mm.

Ordering Information: To order the monochromator, select a grating and slit assemblies based on the intended use as a monochromator or spectrograph. The document provides model numbers and specifications for each component.

Key Features: The monochromator provides twice the dispersion of a 1/8 m instrument, low stray light, and a wide F4/4 cone. It is manually operated and supported by a range of slits and gratings.

With 0.1 nm resolution, the versatility of a monochromator or spectrograph, low stray light, and wide F4/4 cone, the 77200 is a smart choice for applications not requiring the automation of our multi-grating, motorized Cornerstone 260TM instrument (described on page 1191). This is a simple, manually operated 1/4 m instrument supported by a large family of slits and gratings. Optical Configuration Fig. 1 shows the optical configuration of this Monochromator: an in-plane asymmetrical Czerny-Turner configuration. Placing the entrance and exit slits asymmetrically, with respect to the grating, allows the zero coma point to be located within the working wavelength range. This results in minimal aberration throughout the range. Fig. 1 Optical configuration of 77200 1/4 m Monochromator. Interchangeable Gratings The grating assemblies for the 77200 are 50 x 50 mm replicated gratings, prealigned in a protective frame. The frame has a tab so you can insert and remove the grating without touching its surface. Three Types of Slits We offer three types of slit assemblies for the 77200, in various slit sizes. Choose the same type and size for the input and output. Our slit assemblies have a 1.5 Inch Series male flange. Micrometer Driven Slit Assembly • Slit width is continuously variable from 4 ìm to 3 mm • Slit height is adjustable from 1 to 15 mm • ±10 ìm repeatability • ±10 ìm accuracy from 4 to 250 ìm; ±5% from 250 ìm to 3 mm Multiple Fixed Slit Assembly • 8 fixed slit positions from 50 ìm to 3.16 mm • Slit height is adjustable from 1 to 12 mm Fixed Slits • Most economical for single slit size • Fixed width and height • Versatility and high performance at an affordable price • Fast, F/4.4 optics • Wide spectral range - 180 nm to 24 ìm with interchangeable gratings • Twice the dispersion of 1/8 m Monochromator LATERAL LATERAL M3 M4 M1 M2 SIDEBYSIDE
