תלילות קצה ורוחב מעבר
Longpass and shortpass filters are often selected by edge position, but transition width and blocking depth determine real system performance.
מסנני קצה Longpass ו-Shortpass
השוו מסנני קצה Longpass ו-Shortpass לפי אורך גל cut-on/cut-off, תלילות מעבר, חסימה והעברה. בחנו מפרטים לפלואורסצנציה, ראמן וראייה ממוחשבת לפני בקשת הצעת מחיר.

איך לבחור
השתמשו במסנן Longpass כשיש להעביר אורכי גל ארוכים מקצה המעבר ולחסום קצרים יותר, וב-Shortpass להפך. אשרו אורך גל קצה, תלילות מעבר, טווח חסימה, זווית פגיעה ואפשרות שילוב עם מסנני פס עובר.

מסנני Longpass ו-Shortpass
מסנני Longpass ו-Shortpass של OPTOStokes מספקים מעברי קצה חדים להפרדת אורכי גל במיקרוסקופיית פלואורסצנציה, ספקטרוסקופיית ראמן ומכשירי אופטיקה. מסנני Longpass מעבירים אורכי גל ארוכים מקצה ה-cut-on וחוסמים אורכי גל קצרים יותר; מסנני Shortpass פועלים הפוך. ניתן לשלב אותם עם מסנני פס עובר כאשר נדרשת ברירה ספקטרלית מדויקת.

הערות טכניות קשורות
שילוב מסנני קצה
A longpass and shortpass pair can define a custom passband when a standard bandpass option is not available.
הגנת גלאי
Use edge filters to suppress unwanted source energy before it reaches sensitive detectors, especially in broadband or high-power systems.
שאלות נפוצות
מה ההבדל בין מסנני Longpass ו-Shortpass?
A longpass filter transmits wavelengths longer than its edge; a shortpass filter transmits wavelengths shorter than its edge.
מה משמעות אורך גל cut-on או cut-off?
It is the edge wavelength where the filter transitions between blocking and transmission.
האם ניתן לשלב מסנני קצה עם מסנני פס עובר?
Yes. Edge filters are often combined with bandpass filters to improve blocking or shape a more specific spectral window.
