Der Betrieb bei den Grenzwerten beeinflusst die Lebensdauer. The operation at the maximum ratings influences the life time. Zur Leistungsmessung wird die gesamte Lichtleistung in eine Ulbrichtkugel eingekoppelt. Optical power is measured by coupling into an integrating sphere. Die Entstehung von Kondensflussigkeiten mu ausgeschlossen werden. Bedewing has to be excluded.

Standardbetriebsbedingungen beziehen sich auf 2 W cw optische Ausgangsleistung. Standard operating conditions refer to 2 W cw optical output power. Optische Leistungen werden mit einer Ulbrichtkugel gemessen. Optical power measurements refer to an integrating sphere. Modelle zur Bestimmung des thermischen Verhaltens bzgl. des Schwellstroms: Ith(T2) = Ith(T1) x exp (T2 - T1)/T0 Model for the thermal behavior of threshold current: Ith(T2) = Ith(T1) x exp (T2 - T1)/T0

Alle Laser werden vorgetestet und gema den gemessenen Kennwerten ausgeliefert. Bezuglich Sicherheit, Verpackung, Behandlung, Montage und Betriebsbedingungen lesen Sie bitte sorgfaltig unsere Notes for Operation I". Mechanische Montage Befestigungsloch (geeignet fur M 2.5). Durch die gute Waremeleitfahigkeit der TO-220 Bodenplatte (Kupfer) wird die Warme auch bei Befestigung an nur einer Seite gut abgeleitet. Zur exakten Positionierung des Gehauses und anderer Teile, z.B. Linsen, kann das TO-220-Gehause mit entsprechenden Klemmen oder Schrauben (max. M 2.5) befestigt werden. All devices are pretested and will be delivered including measured laser characteristics. For safety, unpacking, handling, mounting, and operating issues, please read carefully our "Notes for Operation I". Mechanical Attachment Mounting hole (suitable for M 2.5) Because of the good thermal conductivity of the TO 220 base plate (copper) the heat loss is properly dissipated even if the component is attached on one side only. For exact positioning of the TO component and other parts, e.g. lenses, the TO 220 package can be attached with appropriate clamping devices or screws (max. M 2.5).
