Osram 520nm激光管,532nm激光管,欧司朗绿光激光管 (520nm) in lots of 100 is 600 yuan or $96 USD
On this other site below similiar prices.
Buy 10 or more Osram PL520 the price is $95 USD
OEMs dealing directly with senior management from companies like Osram, Nichia, Sony and Soraa for 100,000s units will excel the price drop for DGLs
Sentiment: Strong Buy
So we were told for some years ( in several CCs ) that DGLs would start in the mid $20. range and quickly go to single digitt pricing,
They've claimed that DGL availability has been a non-issue for a year now.
So...why the higher prices...still?
Can they blame this on slower than anticipated ramp to mass production and fewer sources than promised by this time?
Did MVIS lie...or were they lied to...or both?
Just looking at a timeline being detected beyond all credibility and wondering who's to blame.
Thanks as always for your DD!
The problem is that the Microvision ShowWx+ required a 72mW 532nm Green laser to support 15 lumens. Based on this, a 520nm Green at 50mW would only support about a 7 lumen Microvision LBS projector. What is the market value today of a 7 lumen projector?
The ShowWX+ did not "require" 72mW to produce 15 lumens. They required 60mW but the only available SHGL was the 72mW. OSRAM uses DPSS based on on of their own 808nm emitter. It probably ended up being 72mW.
Corning was going to produce the 80mW G2000, they demonstrated it with Microvision and Opus Microsystems, and it was sufficient to produce 20 lumens.
Providing outstanding solutions for these tough requirements, the Corning G-2000 green laser:
generates 80mW of optical power, enabling up to twenty lumens projection;
provides a power-efficient solution with 8% wall-plug efficiency (WPE), and longer battery life;
delivers excellent bandwidth capability with modulation speeds up to 150 MHz, enabling wide extended graphics array (WXGA) resolution;
ensures consistent green power across a 10-60ºC temperature range, providing thermal stability over wide temperature ranges and extended use periods; and
is designed with a 4 mm height and slim footprint that enables embedded microprojection in today’s ultra-slim mobile devices.
Still doesn't change the fact that 50mW is insufficient for the task at hand. 25+ lumen projectors.
Slight correction, for a 520nm green at 50mw would be about 8 lumens, the 7 lumens would be for 515nm at 50mw. For future reference comparing to 532nm:
515nm has about 69% as many lumens per mw
520nm has about 80% as many lumens per mw
525nm has about 90% as many lumens per mw
The numbers above are based on the CIE 1931 eye sensitivity function V(λ) in the photopic vision regime.
no market for a 7 lm projector. but there is interest in a 15 lm projector using a 532nm DGL.
i wonder what MVIS is using in their lab to say they can get to 25lm.
i wonder what prices are when ordered by a million.
what i'm really interested in is: what a phone company can get using their tech and what can apple get using their ipad tech.
uhh, the ipad's battery, with apples OS and money. makes a great pairing with the picop.
by the way. MVIS uses a striped down GL (no casing). so the price we see have that price added in.
