For each application or experimental setup we can propose both a technologically advanced solution and an easily sustainable (from an economic standpoint) alternative.

Main products we sale foreign are Mightex Instruments spectrometers and CCD. You can find below a general description of Mightex products or contac us for further details.

USB 3.0 CMOS

Mightex’s ultrafast USB 3.0 cameras are designed for applications that require high-speed and/or multiple cameras. These cameras are equipped with a super-speed USB3.0 interface that can deliver a transfer rate of up to 400 Mbytes per second, which is 10 times the USB2.0 speed, 3.5 times GigE speed and 6 times Firewire-800 speed.

With the 1.2MP Global Shutter CMOS sensor, the frame rate can be as high as 44 fps in full resolution and up to 300fps using ROI mode. Mightex USB 3.0 cameras are optimized for machine-vision applications, and they can also be used for a wide variety of other applications such as digital microscopy and medical imaging, where quality, ease of use, and cost-effectiveness are crucial.

These cameras have external trigger-in, strobe-out, and a powerful camera engine that supports multiple cameras. In addition, a user-friendly GUI based application software and an SDK are provided for custom software development.

SPECTROMETERS

Compact CCD spectrometers are widely used in process control, environment monitoring, and scientific research applications. Mightex HRS series compact CCD spectrometers features a high-resolution 100mm Czerny-Turner optical platform coupled with a Toshiba 3648-element CCD array.

The optimized optical path yields both high spectral resolution and high light collection efficiency. Wavelength and amplitude stability is often a critical requirement for many spectrometer applications. All optical components in the HRS series spectrometers are mounted directly on a single-piece base without using screws. A box enclosure structure further increases stiffness of the base. The proprietary mounting method ensures high stability over time and temperature change.

The spectrometer takes input through a SMA connector port. Usually a fiber patch cord is used to transmit light into the spectrometer. However it’s also possible to send the input light directly into the spectrometer through the input slit. Input ports are interchangeable so that ports with different slit size (or without slit) can be used. Note that wavelength calibration is necessary after changing the input port.

A 16-bit DAC is used to convert the analog signal from the CCD array into a digital stream. The electronics hardware also includes trigger input and four programmable digital I/Os for interfacing with other equipment such as a light source. The spectrometer is controlled through a USB2.0 interface which also supplies all the electric power needed to operate the spectrometer.

Standard software package includes a full-featured PC software as well as a software development kit (SDK) for further software development. Low level USB protocol is also provided in the software package, which supports embedded system based applications.

SPECTROMETERS Accessories

CAL-SPC-AICETC Absolute irradiance (NIST traceable) calibration service for Mightex spectrometers, with exposure time linearity calibration. [ Note: Calibration can only be done on a system level which includes a fiber and/or a cosine corrector (ordered separately).]

Cuvette Holders

The SPC-CVH-10-xx Cuvette Holders accept a standard 10-mm path length cuvette for liquid or powder samples. SMA-terminated optical fibers are used to couple light sources and spectrometers to the device. The Cuvette Holder is compatible with Mightex’s fiber coupled LED sources, Mightex’s spectrometers, as well as any other light sources or spectrometers with SMA termination. The standard configuration of a SPC-CVH-10-xx Cuvette Holder comes with two SMA fiber collimators, with the option of adding up to a total of four (4) SMA fiber collimators. This compact design can easily be inserted into a lab setup, and there is a filter slot on the holder which is perfect for fluorescence applications.

Spectrometer Slits and Input Adapter

These are additional spectrometer input adapters for Mightex’s optical spectrometers. Please note that one only needs to order the adapters if one needs ADDITIONAL input slit, as the original spectrometer already includes a slit.

For customers who require spectrometers without an input slit, an input adapter (ACC-SPC-ADP-0000) is required.

Direct-Coupling Collimators

Direct-coupling collimators are used to either coupling light from free space into a spectrometer or collimating light from a point light source to form a collimated (parallel) optical beam. Direct-coupling collimators are key components with numerous applications. For example, in spectroscopy, a direct coupling collimator can collect light in a narrow field of view into a spectrometer. In another example one collimator is connected to a point light source and the collimated beam passes through a cuvette. On the other side of the cuvette a second collimator couples light directly into a spectrometer. To maximize transmission wavelength range Mightex direct-coupling collimators feature a single BK7 or UV fused silica lens without optical coating. The collimator housing is machined from aluminum alloy for maximum durability. The collimator features an internal SMA thread for direct connecting to spectrometers with popular SMA input ports. When installed on a spectrometer, the full field of view (FOV) or full divergence angle can be calculated as FOV = 2atan(W/2f) where W is the width of the entrance slit of the spectrometer and f is the focal length of the lens. Alternatively, the linear field of view on an object placed a distance L away from the collimator is W(L/f). Focusing of the collimator is adjustable for object distance between 50mm to infinity.
