Overview
OE3001 optical chopper is high-precision optical equipment with its chopper frequencies from 1 Hz to 10 kHz. With the advantage of PID technology and high-quality motor, the frequency accuracy of OE3001 is up to 0.5%. OE3001 consists of a console, a chopper head and a control line. The main function of the console is to control the speed of the motor to achieve the target speed. The chopper head is mainly composed of a base and a motor with a blade.
With a 320*240 color LCD display and a control knob on the front panel, OE3001 can be set to the specific chopping frequency that users need. All the functions can be implemented by rotating and pressing the control knob.The blade of OE3001 can be replaced with different slots blade to achieve different chopping frequency ranges.The standard blade is 10-slot blade with chopping frequency from 20 Hz to 1000 Hz.For other suitable blades and corresponding frequency ranges, please refer to the table below.
High Precision Design
The OE3001 controls and sets up the chopper's functions through a 320*240 pixel 2.4 inch LCD display, and with the control knob on the front panel (right knob), all functions can be realised by rotating and pressing the knob.The OE3001 can be used to change the chopper's frequency range through the use of different blades. The OE3001 comes standard with a 10-slot blade, which corresponds to the reference output signal range of 20 Hz to 1000 Hz. Other applicable blades include 2-slot, 10-slot, 15-slot, 30-slot, 60-slot, 100-slot, and 5/7-slot (the user can purchase the desired blade upon request).
