Preparing Cameras without Sensor Cover Glass

Alvium, Manta, Prosilica GT

V3.0.1

2022-Sep-27

1. Terms used in this document

2. Scope

RCG and TCG cameras must be handled with utmost care to avoid damage to the image sensor. Follow the 

instructions in this document to properly prepare RCG or TCG cameras for operation. 

3. Safety notes

3.1. Electrostatic discharge (ESD)

Electrostatic charge builds up in the body when walking on carpeted floor. This can discharge when 

touching metal objects like a door handle. Such ESD can damage electronic devices, especially when tools 

or hands get in contact with connectors. We recommend measures to avoid damage by ESD:
• Unpacking: Remove the camera from its anti-static packaging only when your body is grounded.
• Workplace: Use a static-safe workplace with static-dissipative mat and air ionization.
• Wrist strap: Wear a static-dissipative wrist strap to ground your body.
• Clothing: Wear ESD-protective clothing. Keep components away from your body and clothing. Even if 

you are wearing a wrist strap, your body is grounded but your clothes are not.

3.2. Sensor damage

Follow the instructions thoroughly to avoid damage to sensor and camera. Work in a dust-free environment 

(class 100 or better) with humidity according to ESD requirements.
