該應用程式可讓您非常輕鬆地測量不同光源的主波長。該應用程式利用智慧型手機相機感測器的先進功能,結合複雜的演算法,盡可能準確地分析入射光並確定其主波長。這項技術開啟了一個充滿可能性的世界,讓您深入研究我們環境中光譜的複雜細節。
對於只有一種波長的光,例如來自常規彩色 LED 的光,主波長對應於該光的波長。
測量光
• 找出白色或灰色的表面(一張普通的白紙效果很好)。
• 將相機對準表面,確保僅由您想要測量的光源照亮。
• 此應用程式將顯示光的主波長(以奈米特 (nm) 為單位)、光的頻率(以太赫茲 (THz) 為單位)以及光的週期長度(以飛秒 (fs) 為單位)。
自動警告
當條件不適合準確測量時,該應用程式會提供有用的警告,以幫助您獲得最佳結果。
什麼是主波長?
主波長是色彩科學和感知領域中常用的概念。它是指在給定的顏色混合物或光源中顯得最突出或占主導地位的光的波長。換句話說,它是我們的眼睛感知為不同波長混合中的原色的波長。如果光只有一種波長,例如來自常規彩色發光二極體 LED 的光,則主波長當然對應於該光源的波長。
測量的準確度如何?
準確測量光的主波長比看起來更複雜。在智慧型手機或平板電腦上,由於所有裝置都彼此不同,情況變得更加複雜。將測量結果視為上帝的近似值。確保您始終使用白色表面,並且只有您想要測量的光線照射到該表面。另外,請避免手或設備產生任何陰影或反射。如果這樣做,測量結果將是相當好的估計。而對於親戚
測量,即比較不同光源之間的主波長,使用同一台智慧型手機或平板電腦,如果滿足上述條件,則測量結果良好。
請注意,智慧型手機相機在區分不同的極短(UV、紫外線)或極長(IR、紅外線)波長時有其限制。更具體地說,在許多設備上,465 nm 以下和 610 nm 以上的精度非常有限。這是由於設備中的實體相機感測器造成的。對於這些短波長和長波長,螢幕上會出現自動警告。

Appears useless. Says aim the camera at a white surface, not the light source. So have to try to bounce the light source you are measuring off something white. With my computer screens 'bounced' it flips between extreme pure red and extreme deep blue. Obviously wrong. All other locations around the house/garden read around 570. All the time it says "saturation is low, so the accuracy might be low too". So direct light is too bright; medium-bright is too low. Always a warning on screen.

Very good app. I am using infrared lamp and wanted to test the frequency. Since the camera of phone limits accuracy, the app gave a range of frequency and I was very happy to test it OK various led lights. It gave good results from uv to infrared.

It has potential but what I really needed is a full spectrum analysis across the entire spectrum with a chart not simply the dominant wavelength because I want to see how much blue light is being produced rather than simply the dominant frequency. That would be similar to an audio spectrum app where you can view the entire audio spectrum in real time as you speak and see the spikes in various wavelengths

I was looking for a spectrometer to match my wall to the paint I have. It showed it wasn't a match. VERY IMPRESSIVE. However I didn't keep my subscription since I'm not sure how to go to the paint store and get an exact match. Do I tell them the number? At any rate a great app and easy to manage subscription and all at a fair price.

well worth it but another app ripped my card I must've forgot to do something but the app ain't on any of my devices to unsubscribe it in play store when you go to not installed not there either . mcard looking into it I'm sorry somebody ate your sale from me Monday or Tuesday 🫂🗽⚖️sumday

I installed the app. If I remember correctly I did not have to select anything and it showed something (do not know if it really worked). I forgot about the app and when I tried to run it again it said "Your trial period ended". I did not know it was a trial period. I thought it worked with adds or pay for a license. In the end I did not get to try it. How do you spect me to buy something I do not know if it works? You have to make it clear there is a trial period.

Best and very accurate. I buy this one lifetime subscription.

If you're worried about the blue light messing with your sleep and, most importantly, your dopamine levels, this is the app for you! >Find an app and decrease the blue light on all your screens that you can. #sleep #dopamine #bluelight
