The 77250 1/8 m Hand Operated Monochromator is a smart and economical choice for general-purpose laboratory work or academic applications. Interchangeable diffraction gratings allow the 77250 to operate over a very broad wavelength range. Wavelength selection is achieved using a rotating crank and the reading is provided on a large, easy to read display. Interchangeable fixed slits or micrometer adjustable slits allow users to select the desired bandpass. Setup is easy because the input and output slits are directly in line with each other. The 77250 provides good resolution and stray light rejection.

When ordering, select two fixed slit holders and interchangeable fixed slits or choose two micrometer adjustable slits. Fixed slit sizes must match at the input and output ports. Then choose the desired gratings from Newport's broad selection. For custom grating or fixed slit inquiries, contact Newport for more information.
