Instructions for Use of LISST-100X Path Reduction Module (PRM)LISST-100X光程缩短器使用指导1.The glass faces of the PRM glass were cleaned before shipping, a wipe with a clean towel or blow with clean air will remove any dust. For future deployments, ensure the surfaces of the PRM glass are clean before mounting the assembly on to the LISST-100. The glass surfaces are not coated. Also ensure that the instrument windows are clean.在运输之前确保光程缩短器的玻璃柱表面是干净的,用一个干净的毛巾擦拭或用干净的空气吹会带走一部分灰尘.更进一步说,在把光程缩短器安装在LISST-100X之前要确保光程缩短器的玻璃柱表面是干净的,同时也要确保仪器的镜头表面也是干净的。2.Please see sketch . Use the supplied Mounting Screws and PRM Spacers to install the PRM (not too tight- the clamp is plastic) in the LISST-100s laser path so that the assembly is closer to the small window than the larger window of the LISST-100, without the PRM glass touching the Small Window. If necessary, loosen the PRM clamping screw (#4 size) and slide the PRM glass (and Bushing, if installed) such that there is clearance with the Small Window. Hold the glass/ bushing so that it cannot slide out of the Clamp when the screw is loosened. Please see sketch. Use a water dropper to wet the Small Window and the end of the PRM Glass that will press against that window. With enough water on those surfaces, loosen the PRM clamping screw (#4 size) and gently slide the PRM glass against the small window, then re-clamp the screw. This configuration optimizes the performance of the PRM, but care must be taken to ensure that a film of clean water always remains between the Small Window and the PRM glass. Any fouling of that film with air or particles will degrade the Background Scatter File quality and should be readily apparent when evaluating the file.看下面的草图，利用提供的安装螺丝和光程缩短器垫片来把光程缩短器（不能把螺丝拧得太紧，垫片是塑料的）安装在LISST-100X的光池里，使该装置更接近小窗口（激光发射口）并远离大窗口（激光接收口） 不要使光程缩短器的玻璃柱面和小镜头的镜头面接触,如果需要,松开光程缩短器的紧箍螺丝并滑动光程缩短器的玻璃柱(衬套，在安装时)这样就能保证小窗口的清洁，握着玻璃柱/衬套这样就能保证玻璃柱在螺丝松动的情况下滑动时不会从装置中脱落，看下面的草图，用水滴分别蘸湿小镜头表面和玻璃柱的表面并让二者相靠紧，由于有足够的水在二者的表面上，放松光程缩短器玻璃柱的紧箍螺丝，慢慢滑动光程缩短器的玻璃柱到仪器的小窗口，然后重新上紧螺
