BLS-Series Software/TTL Controlled LED Controllers with BNC and 2-pin Aero Connectors Description：

Datasheet

Mightex BLS-SA/PL series BioLED control modules are modularized fully-customizable turn-key solutions for optogenetics, fluorescence excitation, and other biophotonics applications. The control modules are designed to control Mightex BLS-series LED light sources to produce precisely-timed and high-intensity light pulses required in optogenetics experiments to activate channel-rhodopsins (ChR2, ChR1 etc.) and halorhodopsins (NpHR) in order to excite and inhibit neurons.

The control module features a linear LED driver design that eliminates light intensity ripples and oscillations often observed when low-cost buckpuck nonlinear drivers are used. Clean and highly repeatable pulses are critical to quantitative experiments. Both CW mode and pulse modes are supported. The time resolution of the control module is 20us and light intensity can be adjusted with 0.1% increments. Each driving channel on the control module has its own TTL trigger input. Rising edge, falling edge, and follower mode are supported in the trigger mode.

Mightex BioLED light source solutions come with a Windows-based operation software featuring an intuitive yet powerful graphic user interface. A software development kit (SDK) is also provided for user integration into environment such as Labview and Matlab.

An optional touch-screen control pad (P/N: BLS-PAD-000) is available (see photo below), with which customers can control LEDs without a computer.

The control module can also be operated without being connected to a computer or a touch-screen pad. This is because custom-defined pulse sequences can be programmed and stored into the control module (through software), after which the light sources can be operated alone and triggered by external TTL pulses.

Specifications

*. An opto-coupler is used for each trigger input, which can accept voltage from 3.6 ~ 12 V as “H”. Please note that the trigger source should be capable of providing at least 5mA current when it’s “H”.
**. Built-in non-volatile memory allows all the operation parameters to be stored on the BioLED Control Module, thus the device can work without a host connected.
*** It is not recommended to mix Type-A/J LEDs with Type-B LEDs on a single unit of this controller. Please operate Type-A/J LED’s on one unit and Type-B LEDs on another.
