INLINE-TTL-S Inline TTL Shutter is a small mechanical laser-cut shutter that is positioned between two UV/VIS-optical components. The INLINE-TTL-S is an OEM part for use in other equipment. The shutter is controlled by a small circuit board that is powered by a 12 VDC signal. The maximum frequency at which the INLINE-TTL-S can operate is 5Hz (5 shutter cycles per second).
