DIM and PULSE options for the SFA

1,00 €

We offer two optional enhancements for the Model SFA Stereo Microscope Fluorescence Adapter. These are available either as a retrofit or as an add-on to a new system purchase._x000D_
_x000D_
– DIM – Replaces the OFF/ON switch with an OFF/ON/DIM switch. This enables you to vary the excitation intensity._x000D_
_x000D_
– PULSE – Adds a BNC connector on the rear of the light base that accepts a voltage signal to control the excitation source ON/OFF._x000D_
_x000D_
Note – only one or the other of the options can be added to a particular base unit.

Dimmer switch option on SFATarget at max and min excitation
_x000D_ The DIM option adds a combined switch and dimmer control. When you first turn the unit on it is at full power. As you rotate the switch the intensity decreases, reaching ~30% at the minimum setting. You have finer control in the brighter portion of the adjustment range. An intensity indicator (1 – 10) makes it easy to record and repeat preferred settings._x000D_ _x000D_ Why might you want to use a dimming control?
