34 Available options: Entrance slits Different models of slits are offered depending on the resolution requirement. The standard slits are: 25, 50, 100, 250, 500, 1000 µm width and 4 or 8 mm height. The H10-61 FS can accept light directly through either a fixed slit or an SMA fiber connector (optional). Gratings models H1061-UV H1061-UVIS H1061-VIS H1061-VNIR H1061-NIR spectral range (nm) 190-800 250-800 350-900 400-1600 800-3200 peak efficiency 250 350 450 600 1200 linear dispersion (nm/mm) 8 8 8 16 32 Scanning drive mechanism The H10-61 SB features a sine drive mechanism which rotates the grating via a lead screw/sine bar mechanism, which yields high accuracy and linearized spectra, so that discrete wavelengths are sequentially scanned. In addition, wavelengths can easily be read in nm, through a digital counter graduated in 0.2 nm intervals. With the H10-61 FS, we offer different models of stepper motors depending on resolution requirements. The basic model is equipped with a 4 phase stepper motor with 12000 step/360°.

Technical information Before introducing the basic equations, a brief note on monochromatic light and continuous spectra must first be considered. Monochromatic light has infinitely narrow spectral width. Good sources which approximate such light include single mode lasers and very low pressure, cooled spectral calibration lamps. These are also variously known as "line" or "discrete line" sources. A continuous spectrum has finite spectral width, e.g. "white light". In principle all wavelengths are present, but in practice a "continuum" is almost always a segment of a spectrum. Sometimes a continuous spectral segment may be only a few parts of a nanometer wide and resemble a line spectrum. The equations that follow are for systems in air where n 0 = 1. Therefore, l = l 0 = wavelength in air.
