Motorized Optical Attenuator Filter Wheel, 8 Position for 532nm Laser a,a:hover,a:active,a:visited Motorized Optical Attenuator Filter Wheel, 8 Position for 532nm Laser img 2 inch diameter, 8 position optical filter wheel made by Melles Griot for a large biotech company. This was used in a fluorescence microscopy instrument with a 532nm excitation laser. The unit has a fixed 532/10 bandpass filter and 8 ND filters ranging from open to fully blocked. The wheel is attached to a FAULHABER® PRECIstep® AM1524, 15 mm dia. stepper motor. These are 4 wire bipolar steppers with a native 24 steps per revolution. The attached 16A type 11.9:1 gearhead reducer increases the resolution to 285.6 steps per revolution and also improves the torque. The motor can easily be extracted for standalone use. The assembly also includes 2 magnetic home sensors with small magnets in the wheel. The attenuator filters are semi-reflective type made specifically for 532nm green lasers. The filters are approximately OD 0 (open), 0.22, 0.47, 0.66, 1, 2 and 4 with the 8th position blocked.Check our eBay store for a similar filter wheel made for use with a 660nm laser.Motor Specs: Model Number: AM1524-V-24-590-07Nominal Coil Voltage: 24VNominal Current per phase: 0.038APhases resistance: 590 ohmNative Steps per revolution: 24Gearhead Ratio: 11.9:1Geared output Steps per revolution: 285.6Overall Diameter: 15 mmOverall Length :16.4 mmShaft Length: 6 mmShaft Diameter: 1.8 mm Pictures and description Copyright © 2023 Starlight Photonics Starlight Photonics Policies About UsWe are a small company located in the heart of Silicon Valley.
