772B-MIR激光频谱分析仪将迈克尔逊干涉仪技术与快速傅立叶变换分析相结合，可测量于1至12 μm的连续波和脉冲激光器的光谱 特性。 光谱分辨率为4 GHz，波长精度为+/-10 ppm （±0.08 nm at 8 μm)。 假设使用足够数量的激光脉冲 （≥30,000） 来生成干涉 图，则可获得约15-20 dB的光学抑制比。

技术参数：

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.
