295 nm LED Chips

A listed band in its own right

In the company's published wavelength keywords, the 295 nm band is listed between the catalogue's disinfection bands and the 310 nm phototherapy band. It stops short of the 310 nm phototherapy band, and it sits long of the disinfection bands. The catalogue lists the band explicitly, inside its 255–340 nm range, without naming an application for it: the application belongs to the buyer's own specification, which states the target spectrum the design assumes. The supply question is confirming that band, and the ratings recorded for it, for a named model in the enquiry exchange.

295 nm at Jason

The band appears in the company's own published wavelength keywords, alongside the other named bands, and it sits inside both the published 255–340 nm chip range and the 260–320 nm span the company publishes as its main production range. The forms in which this band is supplied — bare die, or a specific SMD package format — are established per model in the enquiry exchange. Ask which spectral and electrical ratings are recorded for the named model in the same exchange, and state the centre-wavelength tolerance the design can accept numerically, as part of the same specification.

Where 295 nm sits among its neighbours

• 280 nm — one of the catalogue's named disinfection bands, with a production history at this company since 2010.
• 295 nm — listed in the company's published wavelength keywords.
• 310 nm — the phototherapy band named in the catalogue.

Specifying a 295 nm device

Send the target centre wavelength and the tolerance your design can accept, the form you intend to build with, and the application the band serves. State the tolerance numerically in the first message, and ask what binning is recorded for the model and what spectral data exists for it, so the confirmation addresses the tolerance itself rather than a nominal centre wavelength alone. Quantities and programme volume belong in the same message, as with every band in this catalogue. State the drive point and the duty the device will run at in the same message, and ask what conditions are recorded alongside the model's ratings.

Confirmation testing at this band

A programme can state its own protocol — centre wavelength, output at the drive point, behaviour over the intended duty — in the enquiry, and ask whether evaluation quantities can be supplied against the named model, and what documentation describes them.

Is 295 nm a disinfection band or a phototherapy band?

Neither — it is listed between them. The catalogue lists 275 and 280 nm among its disinfection bands and 310 nm as its phototherapy band; 295 nm is listed between them. Which band a design uses follows from its own specification, confirmed per model in the enquiry exchange.

295 nm in the catalogue record

The band appears in the company's published wavelength keywords alongside 255, 265, 275, 280 and 310 nm, and it sits inside both the published 255–340 nm chip range and the 260–320 nm span published as the main production bands. No application is named for it in the catalogue.
