Description

A widely configurable 4-wavelength dichroic combiner featuring precisely co-aligned optical paths in a free-space output configuration. All optics and electronics fitted into the ultra compact 'Matchbox' housing. This particular configuration provides up to four wavelengths, which are standard for use in Life Sciences, Food, Metrology and Medical applications. An easy to use PC interface and separate TTL inputs allows full control over the individual wavelengths.

Features:

Four wavelengths
Plug-and-play
Single user interface for all 4 lasers

Advantages:

Space saving design
No optics realignment
Remote PC control

Applications:

Wide field and Fluorescence Microscopy
Flow cytometry
Food sorting and quality
Particle characterization

¹ The optical power can be tuned from virtually 0% to 100% by changing the driving current of the laser diodes. However, other specifications, such as central wavelength, power stability, noise, polarization ratio, beam shape, quality, and circularity are not guaranteed at power levels other than factory preset power. Significantly worse power stability is to be expected at very low power levels, e.g. <3% from specified nominal power.

² The long term power test is carried out at constant laser body temperature (+/-0.1 ‎°C) using an optical power meter with an input bandwidth of 10 Hz. The actual measurement rate has a period of about 20 seconds to 1 minute.

³ Noise level is measured with a fast photodiode connected to an oscilloscope. The overall system bandwidth is from 2 kHz to 20 MHz.

⁴ Measured at 1 m from output aperture between the centers of two most distant beams.

⁵ Break-out-boxes AM-C8 and AM-C3 can be used for conversion of UART communication to either USB or RS232.

⁶ If the break-out-box AM-C9 is used, a PD (Power Delivery) type of power supply can be used.

⁷ Excluding control interface pins and an output window/fiber assembly.

⁸ Whichever occurs first.

⁹ TTL digital modulation up to 10 MHz.
