測光表的不同應用
攝影 也許測光表最常見的用途是在攝影中。 測光表通過確定光線如何影響圖像,幫助這些專家獲得完美的拍攝效果。 入射測光錶測量落在被攝體上的光線。 因此,這些更適合肖像攝影。 相反,反射測光錶測量從主體反射的光。 這種設備最常被風景攝影師使用。 反射式測光錶可幫助專業人士和業餘愛好者了解環境將如何影響他們想要拍攝的鏡頭品質。 牙科和醫療領域 之前的博客文章討論了光度計在牙科中的作用。 牙醫使用固化燈來製造填充蛀牙的模具。 如果沒有測光表,這些固化燈就不可能開發出來。 測光表確保治療燈具有頂級品質,並確保患者安全。 同樣,醫生也使用測光表。 醫生和外科醫生經常使用頭燈來執行必要的程式。 這些設備使用測光表進行測試,以確保它們盡可能清晰。 那些從事醫學界的人需要一些事情是光明的,這樣他們才能看到他們在治療病人時在做什麼。 這些只是測光表的兩種不同應用。 事實上,許多行業都使用這些工具來確定光線如何影響他們的工作。 但是,在專業人士將這種設備掌握在手中之前,這些測光錶必須接受 測光錶校準服務。 幸運的是,這就是Gamma Scientific的用武之地。 我們擁有60年的經驗,我們銷售當今市場上最好的測試設備。 安全是我們的首要任務,我們希望我們的製造商能夠獲得最準確的結果。 欲瞭解更多資訊,請立即與我們聯繫。

如何測量LED的強度
在之前的博客文章中,我們已經討論了汽車行業和牙科領域如何使用LED。 這些只是開始認識到這種照明優勢的兩個行業的例子。 由於LED越來越受歡迎,因此每個進入市場的燈泡都必須符合政府標準。 這件作品將向您展示如何測量LED的強度,以確保一切都是安全的。 發光強度 許多製造商使用發光強度方法測量LED。 從本質上講,發光強度測量特定光的波長。 發光強度是使用每個固體坎德拉的流明來測量的。 您應該知道,這種替代方案並不是收集LED強度的最簡單方法,因為整個過程必須是精確的。 光線距離光源不得超過十英尺。 此外,LED燈必須均勻分佈。 因此,由於一切都必須如此精確,因此您應該研究其他測量方法。 光通量 光通量是收集強度的最常用方法,因為該過程更簡單。 光通量是指光源發出的功率量。 同樣,光必須均勻分佈才能工作。 製造商通常使用 光測量儀 被稱為積分球來實現這一目標。 球體是確定總通量的完美形狀,因為它為光均勻分佈提供了最佳環境。 顏色 如何測量LED強度的另一步是確定顏色。 某些行業希望他們的LED比其他行業更豐富多彩。 因此,確定每個LED是否盡可能亮至關重要。 分銷商可以用來簡化此任務的一個工具是可調光源。 Gamma Scientific的SpectralLED可調諧光源可以為多個光源(包括LED)生成任意光譜。 因此,這些工具可以説明您瞭解顏色如何影響燈光的總功率。 LED 是未來。 這些燈比白熾燈泡更耐用,而且更亮。 因此,您必須付出很多努力,以確保每個擊中支架的LED都符合規範。
