  • ARCLED 8 Channel LED Engine

    I’m happy to announce a new product made by ARC. Over the years I’ve worked with a large number of illuminators, from mercury excitation lamps to laser combiners. I’ve tried to combine the best traits of a light source into this device, while ignoring some of the super-awesome features that drive costs up. Key to this is to be completely flexible in LED selection. This is a “dichroic-less” device, as such, one can select as many close-line LEDs as needed for a given application. In addition, LED’s can be installed after purchase by end-users, should they need to add or modify custom modules to the system. Another great advantage for users is the ability to use a broad spectrum white channel, built into the device with the discrete LED channels. This is a unique advantage over other devices, for in many cases all that is required is a broad spectrum light source and a filter cube. Finally, due to the nature of the design and manufacturing engineering of this product, we can offer this multi-channel exciter at what I believe is the lowest price in the industry, $8,500 USD with 8 LEDs installed.

    Here’s a brief video showing the device, you can purchase it from the online store here.

  • LED, laser, or other PWM control using Triggerscope

    It appears that more and more people want to use PWM control for illumination devices from Micro-Manager and other imaging software. PWM may be used for any number of applications, from high speed pulsing of an LED, or a laser, in order to reduce phototoxicity or just to control brightness, or to drive a DC motor at a varying speed, or to drive a device like a spinning disk to set the PRM. I figured I’d address this using the Triggerscope system controllers. rIn order to support PWM drive over an external device, I wanted a few useful functions to work in MM:

    • PWM duty cycle should be controlled form presets
    • PWM should be called to “off” from a TTL or other “shutter” style command
    • Once off, a similar “ttl on” type command should re-enable PWM at the alst used duty cycle
    • multiple output lines should be supported at different duty cycles.

    Version 407 of the Triggerscope firmware now supports this, and uses the existing driver available for these devices. I’ve made a short demo video showing how this works on an oscilloscope output. I’ll place an option for this on the store. Please get in touch with any questions or post here – thanks!

  • Lumencor Sola Driver for NIS Elements

    Yesterday we received our first shipment of Sola white light LED driven sources for microscopy. I had a chance to snag one and write a driver for it. Price is $300 USD. The driver controls both the shuttering and  ND on the box, and integrates easily into Elements as a shutter and ND filter wheel.

    Please contact me if you are interested!
