Duhhh..... And in this town, where scientific measuring instruments are abundant, they wouldn't call it a serious laser meter either. More of a compact
industrial utility toy.
In THIS town it would be considered a toy, or maybe something for an HVAC type with too much cash on hand. I realize that in LA it is important to
have instruments that can detect IR wavelenths that an engineer can interpret as implying something beyond a brown atmosphere hypothetically exists, or detect a flame source anywhere within a twenty mile radius so the atmosphere doesn't explode when somebody lights up a cigarette. I remember when my brother once got thrown out of a nature photo contest down there for displaying a picture with a blue sky. That was long before Photoshop and the LA judges had apparently never seen a blue sky. But up here further north we ignite subatomic particles with lasers, so nobody believes in purchasing anything that doesn't cost a few hundred million dollars. Probably the thickness of the Dixie cups at the Lab are measured
in angstroms. I have none of that snootiness myself. I'm perfectly happy with my little Pentax spotmeters, but otherwise know exactly the placement of exposures for blue skies from sheer memory; and the only laser I own is so an overweight house cat can get exercise chasing the red beam.
I have used this one and its previous model for years at work to measure projector screens and LCD panels. It cost about $4000 USD. it is useless for photography as it has a response the same as your eye, not film. I compared readings to my Canon SLR and my Pentax spotmeter. The variation in daylight and indoor lighting was up to two stops.
I have an SEI meter but I'm sorry to say that I don't feel I really 'need' the accuracy it is capable of providing. On top of that, it adds 585g+ to the mass of my camera bag. I find that my Pentax spot-meter does an 'adequate' job. I've come to the conclusion it might be 'better off' in someone else's camera bag. I have been giving some consideration to putting it up for sale.
