How to unpack and install the Zygo Mark II 4-inch interferometer system?

System composition and technical parameters

（1） System core module

Mark II host: The core function is to collect real-time interference patterns, including a 632.8nm circularly polarized output HeNe laser (replaceable on site), laser power supply, beam splitter spatial filter (BDSF), CCTV camera, and a sealed optical cabin to protect precision optical components. It is equipped with accessory sockets (for installing transmission components) and a remote control box (connected by cables).

Video monitor: Display real-time interference patterns collected by the host, 9-inch diagonal screen, equipped with a universal bracket, can be placed on the desktop or installed above the host through a dedicated lifting bracket, supporting flexible adjustment of viewing angle to optimize observation effect.

Optional VP-2 video printer: uses specially coated paper to provide hard copy recording of interference fringe patterns for easy archiving and analysis.

Laser Radiation Safety Regulations

Laser characteristics and risk warning: The host emits visible red light, with no harmful invisible radiation. The radiation power is less than 1 milliwatt (1/1000 watt), the wavelength is 632.8nm, and the irradiation time exceeds 0.25 seconds. It cannot burn or drill holes, but it is necessary to avoid direct viewing of the beam and strong light reflection to prevent eye damage. Skin contact is not harmful.

Classification and compliance standards: Complies with ANSI Z136.1-1980 standard and belongs to "low-power Class II laser"; Comply with the regulations of the National Center for Devices and Radiological Health (NCDRH) under the US Food and Drug Administration (FDA) effective August 2, 1976 (for laser products manufactured after August 1, 1976), and meet the DHHS radiation performance standards (21CFR Chapter 1, Subcapter J).

Safe operation and identification

Control usage: Only operate control buttons, adjust parameters, or execute procedures as specified in the manual. Violation may result in hazardous radiation exposure.

Key components: The front panel of the host has a green radiation emission indicator light (which lights up when turned on and indicates Class II radiation), and a "BEAM ATTEN." beam attenuation knob (pull out to turn off the laser, push in to turn on); The laser head and power supply need to use Zygo original accessories, and replacement should follow the process outlined in Service Manual SP-0038 to ensure compliance with federal radiation standards.

Identification location: There are certification and patent labels (US Patent No. 4201473) and model serial number labels on the back of the host; At the top (when installing the aperture converter), there is a sign that reads "Laser radiation is emitted from this aperture to avoid exposure"; After opening the lid, there are labels such as "Damaged Seal Invalid Warranty", "High Voltage Warning", "Laser Radiation When Opening, Avoid Direct Exposure" (see Figures 3-1 to 3-3).

Unpacking and installation setup

（1） Installation environment and equipment placement

Stability requirement: The host is recommended to be placed on an optical workbench (such as a granite or honeycomb air cushion platform), with a horizontal beam emitted from the right side of the equipment, making it easy to place the test piece and auxiliary components on the same platform and flexibly adapting to various testing scenarios.

Installation flexibility: In addition to the standard horizontal beam setup, the host can be installed with vertical upward/downward light output; The remote control box and movable monitor enable the host position to be optimized independently of the testing setup, suitable for laboratory prototype development, production testing, and other scenarios. It can also support multiple sets of testing setups on one host through the use of a MUX cube or mobile host.

（2） Unpacking and Inspection

System inventory: The packaging box should include the host, video monitor with bracket, lifting bracket and accessories (hardware, monitor power cord, BNC coaxial line), "Interference Pattern Interpretation and Evaluation Manual" (including mechanical parallelogram), acquisition target, "Operation and Maintenance Manual OMP-0055", "Service Manual SP-0038"; If the packaging box is damaged, please contact the shipping party immediately.
