Featuring a direct-drive 2-phase stepping motor and microstepping controller, it enables ultra-fast filter switching in under 250ms. With built-in USB and RS232 connectivity, it integrates seamlessly into automated systems or manual workflows, reducing desk clutter and enhancing imaging efficiency. ## Description The Filter Wheel with Integrated Controller is intended for changing filters in the excitation light path of Olympus BX fluorescence microscopes. The filter wheel provides fast computer-controlled or manual switching of filters. It can accommodate 10 filters, 32mm 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, M3, M2.5 (included). Parts included: filter wheel, replacement collar, wheel cable, power supply, RS232-RS485 converter, USB-RS232 converter, serial cable, 12 filter screws, light block, tools. 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: 32mm, 10 filters. - Switching time: < 250ms between adjacent filters for fully loaded wheel. - Extension of optical path: 33mm. - 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. ## Product Details - **Material:** Aluminum alloy - **Brand:** TOFRA - **Manufacturer:** TOFRA ## Images ![Filter Wheel with Integrated Controller for Olympus BX series microscopes, 10 position, for 32mm filters - Image 1](https://m.media-amazon.com/images/I/81WDW4+PM8L.jpg) ![Filter Wheel with Integrated Controller for Olympus BX series microscopes, 10 position, for 32mm filters - Image 2](https://m.media-amazon.com/images/I/81WQpc+2mPL.jpg) ![Filter Wheel with Integrated Controller for Olympus BX series microscopes, 10 position, for 32mm filters - Image 3](https://m.media-amazon.com/images/I/81sm-MHVUeL.jpg) ![Filter Wheel with Integrated Controller for Olympus BX series microscopes, 10 position, for 32mm filters - Image 4](https://m.media-amazon.com/images/I/81ELZfmhBxL.jpg) ![Filter Wheel with Integrated Controller for Olympus BX series microscopes, 10 position, for 32mm filters - Image 5](https://m.media-amazon.com/images/I/511ZJpJVL2L.jpg) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/41131127-filter-wheel-with-integrated-controller-for-olympus-bx-series-microscopes](https://www.desertcart.co.uk/products/41131127-filter-wheel-with-integrated-controller-for-olympus-bx-series-microscopes) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
