Fluorescentni materijali izrađeni su od metalnog (cink, krom) sulfida ili oksida rijetkih zemalja i aktivnog agensa u tragovima kalcinacijom. Boja je općenito bezbojna ili svijetlo bijela. To je vidljiva svjetlost (400-800nm) raznih boja pod zračenjem ultraljubičastog svjetla (200-400nm), ovisno o vrsti i sadržaju metala i aktivatora u pigmentu. Fluorescentni materijali apsorbiraju svjetlost certificiranog...

Uvod Mjerenja kolorimetrije i CRI vrlo su važna u raznim industrijama, uključujući rasvjetu, tehnologiju zaslona i znanosti o materijalima, među ostalima. Integrirajuće sfere su se posljednjih godina pojavile kao nezamjenjivi alati za točnu procjenu boja. Ove sfere pružaju kontrolirano okruženje za osvjetljavanje uzoraka i prikupljanje reflektiranih ili tr...
Kompozitna komora za ispitivanje slanog spreja, poznata i kao programibilni kompozitni stroj za ispitivanje slanog spreja, probija koncept tradicionalnih komora za slani sprej. Osim što ima funkcije uobičajenih strojeva za testiranje slanog spreja, također kombinira funkcije izmjeničnog (cikličkog) testiranja slanog spreja, pružajući ispitna okruženja kao što su idiomorfna korozija i filamentna ...
What is a integrating sphere: The integrating sphere is also known as a hollow sphere with a highly reflective inner surface. It is mainly a high-efficiency device that collects the scattering or emission of light by samples placed inside or outside the ball and close to a certain window, or the light emitted by the light source itself. It can be used to accurately measure the optical reflection ...
Što je test užarenom žicom? Ispitivanje užarenom žicom služi za ispitivanje stabilnosti elektroničkih i električnih proizvoda dok rade. Sama užarena žica zapravo je prsten otporne žice s fiksnom specifikacijom. Tijekom ispitivanja užarenom žicom, ona se mora zagrijati na određenu temperaturu strujom, tako da vrh užarene žice dođe u kontakt s uzorkom standardno vrijeme, a zatim promatrati i mjeriti...
Introduction: The reliability of electronic components and systems against ESD occurrences is largely determined by the results of ESD testing. During testing, electrostatic discharge (ESD) guns are often employed to simulate regulated ESD pulses. However, it might be difficult to establish which ESD gun type is the best match for your testing needs due to the market’s abundance of such prod...
Introduction Due to the fact that the durability and reliability of electronic devices are directly proportional to their level of water resistance, IP waterproof testing equipment is an absolute need. Even though there is general familiarity with the IP waterproof testing ideas, recent technical improvements have resulted in a number of additional capabilities that are more advanced. In this arti...
In recent years, LED-based portable spectrophotometers have seen a rise in popularity as a result of the several benefits they provide in comparison to conventional spectrophotometers. In this post, we are going to talk about the benefits and drawbacks of portable spectrophotometry that is based on LEDs. Advantages of LED-Based Portable Spectrophotometry Portability: The most major advantage offer...
