About ASI’s LEDs

ASI’s high intensity LED lamp source and driver is a simple way to provide transmitted light illumination, or even epi-fluorescent excitation when appropriate LED color is used. For transmitted light a white LED is used. LEDs are available in a range of colors with typically 20-30 nm spectral half-widths for fluorescent excitation. The LEDs are rated at 3W and can supply ~100 mW of luminous intensity depending on the specific LED wavelength. Using several beam splitter cubes and LED lamps, it is possible to construct a multi-color LED excitation system with these off-the shelf parts.

For Epi-Illumination Applications

C60-LAMP-ADPT(Universal Lamp Adapter) allows the MIM-LED-LAMP to be placed on the image side of a C60-TUBE-xx lens assemblies to make it into a excitation light condensers that can generate a collimated light. The lamp adapter contains a field stop aperture.

LED Drivers

The MIM-LED-LAMPS can be ordered with one of two kinds

  4. Only LED Engin LEDs are available with MIM-LED-LAMP
  5. Lens assembly used to measure the Power mimics the condenser assembly on a microscope. This was done to better estimate the power the LED would deliver to the objective.

Differences between MIM-LED-LAMP-NR and MIM-LED-LAMP

MIM-LED-LAMP

  • It has an onboard LED Driver. It can be used stand-alone or with our controller.
  • The one available TTL Out on our controller and Tiger plug-in cards is used to generate a PWM to control the brightness of the illuminator.
  • TTL Out will not be available for other uses, and adding another MIM-LED-LAMP isn’t possible.
  • The TTL Out port produces a PWN frequency around 1 KHz; low frequency can cause small camera flicker.

MIM-LED-LAMP-NR

  • It does not come with an onboard LED Driver, and it will required TGLED card to drive it.
  • TGLED has a dedicated PWM driver which frees up TTL out ports.
  • A TGLED card can drive up to four (4) MIM-LED-LAMP-NRs.
  • PWM frequency is as high as 97 KHz; this prevents the camera from flicking.

Example Setup

led-setup

The setup to the left is made of the following components:

  • Three MIM-LED-LAMPS-NR , with 455 nm , 523 nm and 640 nm LEDs
  • Two C60-SHORTPORT
  • Two C60-RA 2nd Port Dichroic Sliders 1 mm , with 600 nm and 500 nm Longpass Dichroic
  • Two Zeiss to Ring Adapter , and
  • One C60-IRIS

The Zeiss to Ring Adapter have provision for 25mm Bandpass filters.
