How to choose a cheap spectrometer?

Off-topic Chatter
1

I see several inexpensive spectrometers, and I’m not sure which one to choose for testing my flashlight. Do you have any recommendations?

Such as：little garden , OPPLE M3/M4, Xrite i1 Pro, ColorMunki Photo,etc.

I have little garden and M3(Not yet arrived), but I still want to buy another one.

Xrite has received many positive reviews, but I have a question: How big is the difference between an xrite and Hopoocolor?For example, what are the differences in spectral range, pectral resolution, etc.Hopoocolor has a basic model called HPCS320, the price for a new unit is approximately $300 (I live in China), Xrite i1pro needs to be purchased on a second hand trading website, and it about $140 or more.

Do I need to pay twice as much for the HPCS320？Is HPCS320 much better than Xrite i1pro?

Could someone help answer my question? I would greatly appreciate it.

I’ve bought the HP 320. It doesn’t support TM-30, probably due to software limits, but I might find useful data from the exports. I’m excited to see how it performs.

Can you export the raw spectral data? I have a Hopoocolor HPCS-310 and it’s able to export the raw data, which I then import into ColorCalculator for TM-30.

I also have an Xrite ColorMunki Photo, and I prefer the Hopoocolor. It has higher resolution, 1nm vs 3nm for ColorMunki; and the sensor isn’t as easily overwhelmed by brightness. It also seems to give more accurate results.

Thank you for your response.

I asked producer,and they told me that it can export the raw spectral data. but it hasn’t arrived yet.I’ll try it when it arrived. The model called ‘Hp320’ is made by DUOTONE CLOUD，not Hopoocolor. This one is a bit cheaper than Hpoocolor’s.

I tried it ,and as the producer told me that it indeed can export the raw spectral data.

Do you have the Osram ColorCalculator program? It’ll allow you to input the spectrum values to generate a TM-30 report.

Yes , I konw this program.I’ll try it later,but i am not sure which lamp can be used as a reference.:joy:

These are TM-30 reports about Incandescent Lamp and candle.
The raw spectral data exported from HP320,Is it accurate?

I’m no expert, but it looks good to me.
