Holography Laboratory

Mounting of Laser

激光安装

There is a little bit of overkill in this mount given the size of the mounting posts, but the laser should be mounted rigidly to the optical table. The optical tables in 140 SC are stable enough without being air mounted to make satisfactory holograms.

尽管安装柱的尺寸较大，这个安装结构略显过度设计，但激光应牢固地安装在光学平台上。140 SC中的光学平台稳定性足够，无需空气悬浮即可获得满意的全息图像。

Development of Film

胶片发展

These chemicals are dangerous! Use proper precautions.

这些化学品是有危险的！请采取适当的预防措施。

Developer in the first tray, bleach in the second, and photoflo in the third. An elevated drain plug in the sink maintains a depth of running water for the washes. Handle the film with plastic tongs or some similar tool - the chemicals are caustic, especially the bleach. Wear rubber gloves if you must do it by hand.

第一托盘中放开发者，第二托盘中放漂白剂，第三托盘中放Photoflo。 sink中的升高排水塞保持洗片时的水深。处理胶片时应使用塑料夹或类似的工具——这些化学物质具有强腐蚀性，尤其是漂白剂。如果必须手工操作，应佩戴橡胶手套。

Mounting of Film

胶片安装

The entire process of mounting film, exposing the hologram, and developing must be done in almost complete darkness.

安装胶片、曝光全息图和显影的整个过程必须在几乎完全黑暗的环境中进行。

In the darkroom with the safelight on, carefully remove one piece of film from the film safe and carefully reclose the safe. The film may be cut to size and then placed on one of the glass plates on some paper towel for padding. Place the other plate on top and carefully squeeze the air out and clamp with the paper clips.

在暗房中开启安全灯，小心地从胶片盒中取出一张胶片并小心地重新扣好胶片盒。胶片可以裁剪至所需尺寸，然后放在一张玻璃板上，上面放另一张玻璃板，用纸巾垫好。然后小心地挤出空气，并用纸夹固定。
