772B-MIR激光頻譜分析儀將邁克爾遜干涉儀技術與快速傅立葉變換分析相結合，可測量于1至12 μm的連續波和脈沖激光器的光譜 特性。 光譜分辨率為4 GHz，波長精度為+/-10 ppm （±0.08 nm at 8 μm)。 假設使用足夠數量的激光脈沖 （≥30,000） 來生成干涉 圖，則可獲得約15-20 dB的光學抑制比。

技術參數：

1.Specifi cations are for pulsed laser mode of operation. For CW lasers, operation and specifi cations are identical to model 771B-MIR.

2.Defi ned as measurement uncertainty, or maximum wavelength error, with a confi dence level of ≥ 99.7%.

3.Wavelength axis is calibrated to system’s accuracy specifi cation. (4) Defi ned as the measured full width at half maximum intensity (FWHM) of an infi nitely narrow optical signal.

4.Data in units of nm, μm, and cm-1 are given as vacuum values.

5.Acquisition of 30,000 pulses will result in an optical rejection ratio of about 15-20 dB.

6.Characteristic performance, but non-warranted.

7.For example, approximately 60 s for 30,000 pulses from a 1 kHz pulse rate laser.

8.Required beam height is 5.4 ± 0.25".

9.For use with Windows-based display program. Interface with SCPI can be done using any PC operating system.

10.Instrument height is adjustable (7.25 ± 0.25") for alignment purposes. Bristol Instruments reserves the right to change the specifi cations as may be required to permit improvements in the design of its products. Specifi cations are subject to change without notice.
