The big and light weight Electronic Filter Wheel is coming.
The body is CNC machined from a full block of aircraft grade aluminium.
Very thin design, 20mm ONLY!
The step motor is the heart of the new EFW, which is made by NPM from Japan. You can trust its quality and reliability.
We have two specifications:8*31mm and 7*36mm.
The Electronic Filter wheel can be rotated in both counter clockwise or clockwise direction for filter selection.
Only one USB Cable is enough to power up the EFW, the max power consumption is around 120ma@5V, so you can connected it form the USB2.0 hub of our cooled cameras.
The distance between the filter and sensor is around 10mm when you connect it to ASI1600.
So 1.25 filters won t have vignetting up to F5 focal ratio scope and 31mm filter won t have vignetting up to F2 lens
Our new RGBL filters are recommended to work with ASI1600, it will offer nearly 1:1:1 RGB color balance.
The full EFW Set includes:
8*31mm or 7*36mm EFW body, T2 nosepiece, 1.25 Holder-T2, T2-T2, USB2.0 Cable
1.25 filter requires: threads length shorter than 3mm, height without threads less than 7mm
31mm filter requires: a set of M42 screws and washers needed to fix the filters are included in the package .
