Why GroupGets?

I arranged a heavily reduced price with the manufacturer, in case minimum order quantity of 8 can be met, we can get a substantially lower price on the item. They agreed to ship individually to each customer directly.

    Here is the comparison for your convenience.

    OceanInsight alternative with software and dev kit $4.367

    No source code provided with software.

    Ocean Insight Spectrometer 350nm - 1000 nm $3881.00
    OceanView 2.0 Software From $243.00
    Ocean Development Drivers From $243.00


    Thorlabs Compact 200 - 1000 nm, $3,042.92
    Thorlabs Compact 500 - 1000 nm, $2,157.75
    Thorlabs Compact 350 - 700 nm, $2,157.75

    Thorlabs Software is Windows only, no source code, no development libraries. - free 423 MB package with .NET junk.


    Lumini T: 350 -- 900nm, $1,111.00
    Software with source code included in price, node.js and javascript.

    Windows, OS X, Raspberry Pi, Linux
    Runs in Firefox, Chrome, Safari.
    Web restful API included.
    Allows e.g. server running on Raspberry Pi in a brewery realtime,
    remote monitoring via http client on multiple clients around the world.

    DIY Kits:

    cheaper in material costs, build it yourself, final price depends on how valuable or cheap your time is.
    Limitation in A/D resolution, dynamic range, minimum exposure time, sometimes running on obscure, closed platforms like Particle Photon.

    Software for real work is a pain point here, virtually non-existent.
