## Overview

The Filter Wheel with Integrated Controller for Zeiss microscopes is a high-performance device designed to enhance your microscopy experience. With a capacity for 12 filters, a rapid switching time of less than 250ms, and versatile connectivity options, this filter wheel is perfect for professionals seeking precision and efficiency in their work.

## Description

The Filter Wheel with Integrated Controller is intended for changing filters in the excitation light path of Zeiss fluorescence microscopes. The filter wheel provides fast computer-controlled or manual switching of filters. It can accommodate 12 filters, 25mm in diameter. The filters could be up to 6 mm in thickness. Filters are held in filter wells with a single screw. There is space for an infra-red blocking filter on the side facing the light source. Tools, required for installation: hex drivers 3/32, 5/64, 1/16, 0.05 (included). Parts included: filter wheel, wheel cable, power supply, RS232-RS485 converter, USB-RS232 converter, serial cable, 12 filter screws, light block, optional extenders.  The wheel can be used as part of automated microscope systems. It has a simple, cost-effective and highly reliable construction. The wheel is compact in size. It is 17mm thick, maximum outside dimension of the housing is 180 mm. The case is made of 1/8” aluminum and is very rigid. A knob with filter numbers is mounted on the front of the motor. Current active filter corresponds to the number closest to the controller box. If the wheel is not powered, the knob can be used for manual filter positioning. The Filter Wheel with Integrated Controller does not need any additional control units; it connects directly to the computer serial or USB port via a cable with built-in converter. This innovative design provides cost saving, requires less desk space, and reduces cable clutter.   The key feature of the design is direct drive. Filter wheel is mounted directly on the motor shaft. A stepping motor with 200 steps per revolution is driven by a microstepping controller. A built-in optical switch is used to home the wheel after power up or as needed. Time required to switch between the adjacent filters is under 250 milliseconds.

## Features

- Filter diameter and number: 25mm, 12 filters.
- Switching time: < 250ms between adjacent filters for fully loaded wheel.
- Extension of optical path: 33mm; if extenders are required - 46mm, 53mm, or 59mm.
- Motor: 2 phase, 1.8 degrees per step, 1.1A/phase
- Controller: Microstepping motion controller and driver EZHR17EN from AllMotion, Inc.
- Computer Interface: Serial RS232 and USB with USB-to-serial converter.
- Control Software: WheelTool v1.0 for Windows, direct control through serial port, EZStepper in MATLAB, Micro-Manager Device Adapter.
