该应用程序使您可以非常轻松地测量不同光源的主波长。

该应用程序利用智能手机相机传感器的先进功能,结合复杂的算法,尽可能准确地分析入射光并确定其主波长。这项技术开启了一个充满可能性的世界,让您能够深入研究我们环境中光谱的复杂细节。

对于只有一种波长的光,例如来自常规彩色 LED 的光,主波长对应于该光的波长。

测量光
• 找到白色或灰色的表面(一张普通的白纸效果很好)。
• 将相机对准表面,确保仅由您想要测量的光源照亮。
• 该应用程序将显示光的主波长(以纳米特 (nm) 为单位)、光的频率(以太赫兹 (THz) 为单位)以及光的周期长度(以飞秒 (fs) 为单位)。

自动警告
当条件不适合准确测量时,该应用程序会提供有用的警告,以帮助您获得最佳结果。

什么是主波长?
主波长是色彩科学和感知领域常用的概念。它是指在给定的颜色混合物或光源中显得最突出或占主导地位的光的波长。换句话说,它是我们的眼睛感知为不同波长混合中的原色的波长。如果光只有一种波长,例如来自常规彩色发光二极管 LED 的光,则主波长当然对应于该光源的波长。

测量的准确度如何?
准确测量光的主波长比看起来更复杂。在智能手机或平板电脑上,由于所有设备都彼此不同,情况变得更加复杂。将测量结果视为上帝的近似值。确保您始终使用白色表面,并且只有您想要测量的光线照射到该表面。另外,请避免手或设备产生任何阴影或反射。如果这样做,测量结果将是相当好的估计。而对于亲戚
测量,即比较不同光源之间的主波长,使用同一智能手机或平板电脑,如果满足上述条件,则测量结果良好。

请注意,智能手机摄像头在区分不同的极短(UV、紫外线)或极长(IR、红外线)波长时存在局限性。更具体地说,在许多设备上,465 nm 以下和 610 nm 以上的精度非常有限。这是由于设备中的物理相机传感器造成的。对于这些短波长和长波长,屏幕上会出现自动警告。

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
