Mitsubishi ML520G71...Red Holy Grail or Flashlight Fail ??

[andyf97]

Andy... easy there friend. No offense meant so please accept my apologies if any taken. I disagree that it has been established that these are better than any on the market. They are substantially different in their output and lens requirements and so it is interesting to pursue this route as you have and I look forward to your results. But you will need to better define your optics so others can duplicate as well as add additional knowledge. We can't claim what the cost of the corrective optics is if we don't know the prescription or the source.

I did enjoy a few conversations with Mr. Benner (president of Pangolin) and was favorably impressed with his description of the development work they are doing on an improved actuator (read galvo motor). But, I can't claim he is my friend. I bring this up because like you I am interested in improving the performance of our projectors and I believe that we should keep an eye on the relative cost/ease of each approach. And if the lens component becomes difficult then why not look at the scanner etc.

I didnt take it as offensive, just kind of wearied as the thread is about a diode. Not scanners. send me the thread about these amazing new scanners because I know somebody else who is working on some 200k scanners and its not somebody in USA.

G71 cost for 500mW = 160 usd
Opnext cost for 500mW = 400usd

I can also do that simple math which only factors in diode cost. What no one yet seems to be able to do is do the same for power density with equivalent divergence and factors in the cost of required optics and mechanics.

To me the results would be expressed in mW/square cm with associated divergence. The optics and mechanics costs must be included to make this a fair comparison.

Did you try it?

Andy my friend.... calm down man... this isn't a pissing contest.

We are all here for the same reasons.
We aren't all on the same wavelength but do Love the coherent light..

:-)

HAHAHAHA, I am fine. Trying to help with a new solution, if the help isnt required, I won't.

I will be doing this for the Opnexts. I've not yet heard compelling evidence that these Mitsubishi diodes can match the power density (mW/cm2) with same or better divergence for less cost including optics and mechanics, and I'm unlikely to waste money trying.

This is no criticism of anyone who is, I'm just stating my opinion that without being able to match or better the beam specs for less money these diodes would not be the red holy grail.

Ok ... its nice to read you are fine....thats important.
We are all here to enjoy the hobby

if the help isnt required, I won't.

Come on dude.... thats yet antoher reaction that wasn't nessecary.
We all help each other... with or without you.
Help is welcommed.. but it isn't required... just treat each other with respect

whatever just ignore them and keep working on it... if you can recreate your results this would be really great, the opnext diodes are too fragile and low power... people complaining about optics, don't you need fancy knife-edge setups for your opnext diodes? how much do those cost?

So why comment then ???

Because this topic has question marks at the end and asks if it's the red holy grail or flashlight fail.
