Introducing two new optical shutter systems from SRS — the SR470 Laser Shutter Controller and SR474 Four-Channel Laser Shutter Driver. These shutter systems are designed specifically to minimize vibration on your optical table. They are built around a unique shutter head, supported by one of two available controller models. The SR470 provides timing signals to a single shutter head, while the multi-channel SR474 drives up to four shutter heads, and is controlled by external timing signals.
