High Power LED modules with TEC cooling and optional fibre-coupling The LEDMOD V2 modules offer great functionality and flexibility for applications in industry and research. With more than 40 different wavelengths from deep UV to the near infrared and optical output power of several hundred milliwatts, the so-called “LEDMOD” series can be used in many applications such as microscopy, chemical analysis, spectroscopy, forensics and other areas. The LED modules are available in a fibre-coupled version or with free emission. The modules have modulation inputs for fast analogue intensity modulation with up to 200 kilohertz and digital modulation with a switching time of < 2µs. High-precision temperature stabilization of the LED chips ensures a very good performance and wavelength stability. This is important especially for applications that not only need an exact output power, but also a high stability of the emission spectrum. The digital modulation can be operated via external modulation signals, as well as an internal, programmable signal generator. A SYNC output ensures synchronization with external devices such as cameras, spectrometers and lock-in amplifiers. One or several optional “LEDMOD” modules can be comfortably controlled via RS-232 and USB 2.0 interface by either the supplied software ‘Omicron Control Center’ or the customer’s own software. – Software driver for Metamorph available LEDMOD Series – Specifications LEDMOD V2 Wavelengths & Powers(other wavelengths and powers on request) Deep-UV: 255nm / 150µW * 265nm / 400µW * 275nm / 6mW * 280nm / 600µW * 310nm / 50mW 340nm / 50mW UV / Violett: 365nm / 450mW 385nm / 450mW 405nm / 450mW VIS: 455nm / 450mW 470nm / 450mW 505nm / 100mW 528nm / 100mW 590nm / 100mW 617nm / 450mW 625nm / 450mW IR: 850nm / 800mW 950nm / 800mW White: 5600K / 400mW Free emission angle 120 – 130° (Deep-UV 10°) Temperature control active peltier cooling (TEC) External modulation capabilities up to 500kHz analogue modulation up to 500kHz digital modulation Modulation inputs 1x Analoge modulation (0…5V / 2.5kOhm) via SMA Connector 1x Digital modulation (TTL / 5kOhm) via SMA Connector Internal modulation capabilities Up to 200kHz with programmable frequency and duty-cycle Power setting resolution internal: 12Bit external: analogue SYNC output TTL signal via SMA connector Computer interface USB-2.0 and RS-232 Operation modes 1.) external analogue control (0…5V) for output power and additional external TTL signal for ON/OFF modulation 2.) internal power control with external TTL for ON/OFF modulation 3.) internal power control CW (continues wave) operation(no external signals necessary) 4.) internal power control programmable frequency and duty-cycle for ON/OFF modulation (no external signals necessary) 5.) external power control (0…5V) for output power programmable frequency and duty-cycle for ON/OFF modulation Control interface 15-pin HD-Sub-D connector Dimensions (without fibre-coupling unit) 56x52x166mm (HxWxL).
